General Mach Discussion / Loosing position during movement to part zero position after machining
« on: February 19, 2013, 06:54:42 AM »
Hi folks,
I have a cnc router with a Intel Atom (1.6Ghz) single core with 1gb of RAM as the control PC and running Mach3,
It behaves peculiarly - when running small programs like say which have a time span of less than an hour - the router works perfectly, however when there are programs which run for like 2 hrs or more the last move "g0x0y0Z25" wehere Z 25 is the safe height of the program triggerrs a high acceleration move which results in lost steps on the Z and Y axis as I have noted.
This also happens in another point during use of "run from here" option here say the safe height is set to 25 and the machine tries to get it done so fast that the Z motor just looses its position,
For me it is as if the mach is not able to provide the pulses the way it is set to (on motor tuning) and is pulsing way fast for the steppers to cope up.
Any ideas on why this behaviour - the mechanicals seem to be perfect from my point of view -
I use PP to run my router.
