July 16, 200520 yr I use Mach 2 to run my CNC, and I use ACE converter to get .dwf files to convert in G Codes. I am sure Mach 2 accepts most standard type of G-Codes. I would be greatly appreciated if you could share your G-code on annunicator. That'd help a lot. You can send G-Code through my e mail [email protected] About engraving panels, what type of drill bit did you use? what its length. I was told .2mm fishtail drill bit would be best and I just realize this one can only do large engraving not tiny letters like most panels. Your panel look real good... is it back lit too? The white plastic, is it Lexan or perspex? It's hard to find white plastic around, and I am still researching on it.
July 19, 200520 yr Johan,I'd be interested in the G-code also. I'm now running Turbocnc instead of KCam. I have used your MCP dfx files from your site.DavidPS you should put the gcode up on your download page.
July 19, 200520 yr I can put the G-Code on my download page, the major difference between G-code and DXF files are that the G-code are made to suit specific material, mill speed, mill size, mill type etc.But, I'll put the G-code in a zip file together with a text document that states all parameters that has to be set right to get it work OK.Johan
July 19, 200520 yr JohanI would be interested in te settings of your mill.I use a cnc machine too. Plexi is one of the most difficult materials to mill , I am told. It gets hot very easily and then the material that is removed sticks on your mill. You have to remove it and continu.Slowly I am getting the touch. I use a syring with water and put drops of water aling the track of the mill. I remove 0,4 mm each time. It is very time consuming because I have to stay with the machine and control it.I use the lowest rev settinn (5000 proxxon). What are your experiences with this?RegardsNorbert Boschhttp://home.wanadoo.nl/norbert.bosch
July 19, 200520 yr I only mill in Acrylic, 3mm white or 5mm clear. The acrylic doesn't melt or stick to the mill. I run the mill at 22000rpm with a traverse speed of 100 (set by the G-code on my machine)With this setting, I can start my mill and leave it for as long it takes, then come back to get the finished parts (and clean the room)The G-code with instructions is now available on my website download pageJohan
July 20, 200520 yr >Robid, > Curious... why would you pick TCNC instead of KCam? Just>wondering.Arthur,I was using KCam. I built my own CNC machine so there was a little sloppiness in the Axes. KCams backlash is buggy and skips steps. When you use the backlash, there is no torque in the motor and if the axis is a little tight, it stalls until the backlash amount is taken up.TCNC keeps torque up while taking up the backlash without skipping steps.David
July 20, 200520 yr Johan,Did you make the gcode from dxf or plt files (or similar)?If so, can I get a copy of the above. (Then it won't have the tool offsets)David
July 20, 200520 yr The G-code is made from a DXF file, but I won't share it, Contact me private.johan @ novelair . com (no spaces)Johan
