I hear you.
I have looked at the Gcode and it seems fine. All simulations in artcam are fine.
I have sent a file to Big S and it has worked on his machine.
He has sent me a program that has worked on his machine but it does not on mine. I have tried my USB on another CNC and it ran a simple area clearance perfectly.
I have re booted the DSP
I have reinstalled ZHB981 version to the handpiece.
I then installed ZHB701 version to the handpiece.
i have reformatted the parameters many many times.
tried it in emergency mode.
The bearings seem tight and leadscrews etc have no noticable wear marks etc. There is that flex but i do have to force it to get it. And the machine was working fine. It also seems only at entry and then it cuts perfectly even at full depth of cut. The error can occur in even the softest of materials??
I agree it seems to be ramping into the cut but i have been unable to determine why.I design in Corel, Do the toolpaths in Artcam 8 then take to the cnc via USB stick.
Originally i thought it was USB or DSP???????????????????but i honestly am stumped, I will have got the DSP handpiece from my old(that i know is working) machine and test it on this machine.
i will run a new program when i get this thing back together and email you the gcode for a simple circle..
