 |**Note:** **Be extremely careful never to use the nosecone on your spindle when the spring pressure lockring is down.** You may harm your Z-axis motor, the Z-axis leadscrew and even the controller. In other words, always respect the following principle: Never launch an engraving cycle with both the nosecone on the spindle and the spring pressure lock ring screwed down.  |
-==== De plaatoppervlakte instellen met niet-geblokkeerde veerdrukring en daarna graveren met geblokkeerde veerdrukring ====
+==== Setting the plate surface with spring pressure lockring in the down position ====
-Hierboven staat beschreven hoe de veerdrukring geblokkeerd kan worden, en hoe de neusconus houder ring verwijderd kan worden van de spindel.
+Here above you can read how the lockring can be screwed up and down, and how the nosecone holder ring can be screwed off the spindle.
-Om de plaatoppervlakte in te stellen en zonder neusconus begrenzer te graveren, ga je als volgt tewerk:
+To set the plate surface and to engrave without floating nosecone, follow these steps:
-  - Draai de veerdrukring volledig omlaag zodat de floating spindel geblokkeerd wordt.
+  - Turn the spring pressure ring down as far as possible to lock the floating mechanism.
-  - Trek de transparante stofafzuigslang van het afzuigvoetje.
+  - Pull of the transparent vacuum hose from the dust boot.
-  - Verwijder de gegradueerde neusconus houder ring met de neusconus en het afzuigvoetje.
+  - Remove the graduated nosecone holder ring with the nosecone and the dust boot.
-  - Schroef de frees met de spanknop die je wenst te gebruiken in de spindel en zet ze goed vast.
+  - Put the cutter which you want to use into the spindle and tighthen the cutter knob well (but never use pliers to do so).
-  - Plaats het materiaal dat je wilt graveren op de graveertafel en leg het goed vast.
+  - Place the material which you want to engrave on the engraving table and make sure it cannot move.
-  - Beweeg de spindel ergens over de te graveren plaat. Gebruik daarvoor het virtuele toetsenbord.
+  - Move the spindle somewhere over the plate to be engraved. Use the jog keys on the virtual keypad to do so.
-  - Breng met de Z-omlaag jog toets de spindel omlaag tot het freesje net het plaatoppervlak raakt. Gebruik eventueel een stukje dun papier om te voelen of de Z-positie juist is. Let op: beweeg niet te snel omlaag want zo beschadig je mogelijk het materiaal of je breekt de frees.
+  - Using the Z-down jog key move the spindle down till the tip of the cutter just touches the plate surface. You could use a piece of paper to "feel" if the Z-position is correct. Attention: Do not move down too fast, you might damage the material or break the cutter tip.
-  - Klik op de "stel materiaal oppervlakte in" toets: {{:en:x300:key_surface.png?30}}op het virtuele toetsenbord.
+  - Click on the "set material surface" key: {{:en:x300:key_surface.png?30}} on the virtual keypad.
-  - Klik in dit net geopende venstertje op de “Enter” knop om de plaatoppervlakte in te stellen (Z=0.00). De spindel zal vervolgens omhoog bewegen boven het graveermateriaal.
+  - In this just opened window click on the “Enter” key to set the plate surface (Z=0.00). The spindle will then move up above the engraving material.
-  - Deze procedure impliceert dat de frees het graveermateriaal zal raken. Als dat niet mag, bv. omdat het graveermateriaal zou kunnen beschadigen, kun je een dun plaatje boven op je graveermateriaal leggen, waarvan je de exacte dikte kent. Denk eraan dat de dikte van dit tussenplaatje bijgeteld moet worden bij je graveerdiepte om een correcte gegraveerde diepte te bekomen.
+  - This procedure implies that the tip of the cutter will touch the material. If that is prohibited, e.g. because the material is very critical to scratches, you could place a thin piece of material on top of your engraving plate and follow the same procedure. Measure the exact thickness of this piece and add that to the engraving depth in Symmetry to obtain the correct engraving depth.
-  - Start je graveerjob.
+  - Start your engraving job.
-=== Nota's: ===
+As an alternative to this procedure you could also follow these steps:
-{{:nl:x200:Zmove_fromjobfile.png?600}}
+  - follow the steps from 1 to 6 as described here above.
+  - Using the Z-down key move the spindle down till the tip of the cutter is a few millimeters above the plate surface, but not touching it.
+  - Unscrew the little screw in the cutter knob and gently push the cutter down till it's tip touches the material.
+  - Retighthen the screw in the cutter knob.
+  - Click on the "set material surface" key: {{:en:x300:key_surface.png?30}} on the virtual keypad.
+  - In this just opened window click on the “Enter” key to set the plate surface (Z=0.00). The spindle will then move up above the engraving material.
-Wanneer zonder neusconus en met een geblokkeerd vlottend mechanisme gewerkt wordt, zal de machine de dieptes uitvoeren die in de graveerjob zitten, op voorwaarde dat in het Job dialog venster (zie hierboven) de "Z move values" in gesteld werd op "From Job File". Of je graveerjob dieptes bevat hangt uitsluitend af van de gebruikte software. Sommige programma’s gebruiken Z-omlaag en Z-omhoog waardes, andere programma’s gebruiken alleen “omlaag” en een “omhoog” instructie, zonder opgave van een waarde. In dit laatste geval moet in dit dialog venster de "Z Move Values" ingesteld worden op "From Pendent setting". De graveermachine zal dan een voorgeprogrammeerde diepte gebruiken, die ook ingegeven of gewijzigd kan worden via het “Job dialoog venster” in het virtuele toetsenbord.

-==== Plate surfacing with unlocked spring and engraving with locked spring ====
-In the section here-above you can read how to lock the spring pressure lock ring, and how to take off the nosecone retainer ring with the nosecone and the vacuum boot.
-In order to surface and then to engrave without nosecone, you proceed as follows:
-  - Screw the spring pressure lock ring all the way up, hence unlock the floating movement.
-  - Pull off the transparent vacuum hose from the vacuum boot.
-  - Take off the nosecone retainer ring with nosecone and vacuum boot.
-  - Insert the cutter which you want to use into the spindle and tighthen it.
-  - Place your material to be engraved on the engraving table and make sure it is well secured.
-  - Move your spindle somewhere over the plate to be engraved.
-  - Make sure the “plate surface” indicates {{:en:x300:plate_surface_set_v2.png?100|“set”}}. If not then activate this mode by clicking on the {{:en:x300:plate_surface_set_v2.png?100|“set”}} key.
-  - Click the “set material surface” key {{:en:x300:key_surface.png?30|}} on your keypad.
-  - Click the “probe” button {{:en:x300:probe.jpg?100|}} to begin the surfacing routine. Keep on pressing this “probe” key and the Z-axis will move down slowly until the spindle touches the material. It will then move up above the material surface.
-  - The above mentioned procedure implies that your cutter will touch your engraving material. If you prefer that this does not happen, because of the potential danger to damage your plate, you can use a thin plate in between, of which you know the exact thickness. Bear in mind that the thickness of this dummy plate has to be added to your engraving depth to get the correct depth.
-  - Screw the Spring pressure lock ring down, so that the floating mechanism is completely locked.
-  - Run your engraving job.
-=== Notes: ===
-{{:en:x300:schermafbeelding_2021-06-20_115217.png?300|}} \\
-  - When working without nosecone and with a locked floating mechanism, the machine will execute the depths which are in the engraving job. If your engraving job contains depths depends entirely on the software used. Some softwares use Z-depths and Z-up instructions, other softwares just use a “Cutter down” and a “Cutter up” instruction, without specifying a real value. In the latter cases, the engraving table will use a preprogrammed depth, which can be entered or modified through the “Job dialog window” on the virtual keypad.
-  - Whenever the controller contains values, which show up in the “job dialog window”, these values will only be used if the engraving or routing job in question does not contain values for these specific variables. This is valid on a variable per variable basis. E.g. if the engraving job does not contain depths, but does contain XY speeds, then the system will use the depth which is specified in the “job dialog window”, but the XY speed setting from the job will automatically overrule the XY speed setting which is visible in the “job dialog window”.
-==== Surface mapping with unlocked spring and engraving uneven surfaces with locked spring ====
-If the object you want to engrave has an irregular surface, or if the plate you want to engrave is cast acrylic (PMMA), which can have rather important differences in thickness, and you do not want to use the nosecone because of the risk of scratches or shadows along the engraved characters, then using the surface mapper is a possible solution. Surface mapping a plate surface works as follows:
+{{:nl:x200:zmove_fromjobfile.png?600}}
-  - Remove the engraving cutter from the spindle.
+When engraving without nosecone and with a locked floating mechanism, the machine will execute the cutting depths which are programmed in the engraving job, on condition that the variable "Z move values" in the Job dialog window (see here above) is set to "From job file". If your engraving job contains cutting depths or not entirely depends upon the used software. Some programs use Z-down and Z-up values, other programs use Z-down coordinates but only a Z-up instuction without value.  In the latter case the "Z move values" variable in the dialog window has to be set to "From Pendent Setting".  The engraving machine will then use a preset depth, which can be set or modified in the "Job dialog window" in the virtual keypad.
-  - Remove the vacuum hose from the spindle and then remove the nosecone retainer ring with the nosecone and the vacuum boot from the engraving spindle.
-  - Insert the special surface map rod (option) into the spindle and fix it in the cutter knob when the rod sticks about 10 mm out at the bottom of the spindle.
-  - Make sure the spring pressure lock ring is in the max up position.
-  - Position your object to be mapped on the engraving table and secure it.
-  - Position your spindle in the upper left corner of an imaginary rectangle in which the engraving job has to be executed. This imaginary rectangle is not necessarily the same as the object’s surface, it can be smaller (but not bigger), and set home there.
-  - Make sure the "plate surface" is set to {{:en:x300:plate_surface_map_v2.png?100|"map"}}.
-  - Then click the “set surface” key {{:en:x300:key_surface.png?30|}}, which will make a small window pop up. In this window several variables have to be entered:\\
-  - {{:en:x300:surface_map.jpg?300|}}\\
-  -   * **"X scan distance"**: the width of the imaginary rectangle you want to map. Entering values has to be done by typing the correct numbers on your computer’s keyboard.
-      * **"Y scan distance"**: the height of the same imaginary rectangle you want to map.
-      * **"Step size"**: the distance between each of the points to be digitized, both in X and in Y. If your plate is almost flat and has relatively unimportant height differences, you can use a relatively high value, e.g. 20 or even 30 mm. If your object has a more irregular relief, keep the step size small, e.g. 5 mm. Which value you have to choose with which kind of surface is a matter of trying and building some experience.
-      * **"seek feed"**: the speed at which the spindle with the mapping rod will move down to map each of the points in the mapping matrix. Normally a speed between 5 and 15 mm/sec is adequate.
-      * **"Z Safe Lift"**: Z-up move after mapping each point. You just have to make sure that the lift value is high enough to move over to the next point. Suppose that the relief has a rather steep surface, and that the Z-position of the next point to be measured is 3 mm higher than the last measuring point. It is clear that your Z safe lift has to be bigger than 3 mm, otherwise your mapping rod will crash sideways with your relief.
-      * **"save surface map"**: In normal circumstances you do not want to save the surface map unless you have to engrave a series of objects with identical surfaces. If you want to save a mapped surface, highlight the "Save Surface Map" option and click the "Enter" key. \\ There is a [[:en:x300:surface_map_option|separate chapter]] in this manual, where you can read in detail about the surface mapping option.
-  - Take out the mapping rod from the spindle, put in the engraving cutter of your choice, surface the cutter somewhere inside the imaginary rectangle which has been mapped and run your engraving job.
-  - Your 2D engraving job, with all of its speeds and depths, will be projected on the mapped surface. The mapped surface is a fluid interpolated cloud of points. Although the machine in reality performs a 3d job, for the user it is just a 2D application.
