Tony I have been using gcode metric, as the only post processor I have for my Deskcnc is in inch. Do you have one for metric. Also the 'Z' is getting lost on some files especially on small wording e.g. 10mm high should the 'XY' feed speed run at the same speed as the 'Z' Does a lot of arc's create more file than lines?
Turn on the DeskCNC box or the driver box (which has the DeskCNC. Click on the DeskCNC icon. The 1st message on the screen should be 'Hardware detected'. If you get 'hardware not found' this means that the software on the PC. Usually this message will show if the DeskCNC electronics are not.. Sep 16, 2005 - 3. 3) Setting up the software – Machine Tab 4. 4) Setting up the software – DeskCNC Setup Tab 5. 5) Setting up the software – Axis Setup Tab.
One particular job I am doing were's I drew an animal vectorised it convertered a lot of the lines into arc's size is about 160mm X 230mm no mater what I do with the speeds the 'Z' gets lost I do a lot of this and haven't had as much of a problem as this time and i'm thinking is there to many arc's? Are feeds speeds on small stuff Just trial and error Help! Regards Paul Posts: 44 Joined: Fri Jun 02, 2006 2:36 am Location: Australia. Hi Paul, I have e-mailed you a Metric DeskCNC postp + notes on how to add this to the software. When you say the Z is getting lost, do you mean it's losing steps? The Z plunge feedrate is normally set to be slower than the XY cutting feedrate because cutters don't cut very efficiently on the bottom.
So slowing down the vertical plunge moves helps reduce the loading and give the cutter a chance Toolpaths that contain arcs usually run better than simple point-to-point moves and there shouldn't be a problem with to many arcs in the file. Does it make any difference if you save the toolpaths using the G Code mm (.tap) - no arcs?

With the sign engraving everything has been ok were there is little 3D work just recently the problem seems to have accured We have do a lot of craft work in timber for shops and I have come up with some ideas using Vcarve and the router I am doing a 3D profile then a 2D cut out of animals nice efect. Cutting out 20 at a time in this there is a lot of 3D work and the speeds i'm used to working at it is losing steps. In the Deskcnc setup I have reduced the velocities and doing the toolpaths at 800mm a minute and plunge at 400mm a minute with still a small amount of lost steps the job now takes a long time.
The Desk cnc processor seemed worse and the machine would Zero at 1mm not 0mm not thats a problem just threw me. Tried both Gcode mm and Gcode mm arcs all resulting the same Wonder if the Deskcnc controler card may malfuction I wonder if I should change over to servodrive would like to run this thing faster i'm not sure if I am asking too much of this thing any Ideas. Has anybody got any experince with Deskcnc, Gecko drivers, stepper motors, and motor speed velocities Posts: 44 Joined: Fri Jun 02, 2006 2:36 am Location: Australia. Does the DeskCnc PP work with Cut3d? I'm trying to carve a curved piece of molding and the rough and finish passes run fine but the cutout pass is very choppy while passing through a portion of the curve. At first, I thought I was having some sort of acceleration problem. If I zoom in on the simulated curve in DeskCnc it has a ragged edge along part of the curve.
Why would this be happening? Here is a copy of the g-code. The v3d file is 57mb so I won't try to send it.

Hi Paul, It sounds like you may have a problem with the DeskCNC controller and / or the Steppers.
If you run a sample file at very slow feedrates and acceleration settings on the controller, does the machine lose steps?. Bert, The Cut Out toolpath in Cut3D is only an approximation around the 3D model silhouette. Therefore a lot depends on the smoothness of the model and also the size it's being cut at. Can you send just the 3D model (no toolpaths) to so we can take a closer look. Tony Vectric Alumni Posts: 1965 Joined: Sat Jul 30, 2005 6:24 pm Location: UK.
