Hi All
Been lurking here a bit since building a PRO4824 the last couple of months.
I have encountered a problem that has me baffled!
When I run a program or jog the router on slow speeds the slaved axis on the gantry stops moving throwing the gantry askew and alignment until the gantry is homed against my switches. Another words the slaved motor on the left front side is motionless with the master motor keeps moving in step. The problem is random but more often than not. I have a few other minor kinks but this one make the router unreliable/unusable at present!
I have some familiarity with Mach3, Metal Mills, CNC, etc. The router is a new one to me, particularly the slaved axis setup.
Currently I'm simply trying to do some holes and circular cuts in some mdf and at random the slaved motor stops moving, I sent Ahren at CNC RP an email that didn't really give me any direction other than to advise the motors work in tandem it must be the gcode. However it can occur while simply trying to jog at slow speeds but never at higher speeds. I have listed the technical information below and can supply more if anyone might know what to check further.
Nema23/G540 from CNCRP
PRO4824 CNCRP
MACH3 setup as follows
Motor Velocity 400im/Acceleration 20im for Y/A Gantry Axis. Steps 1736
I have dropped both motors off the rack and can roll the gantry forward and back with one finger no binding anywhere along V-Con Rails. I have checked for pulley slippage. Binding of the V-Con bearings, meshing of the motor to the rack. The bolt tension on the motor gear to the rack from relatively loose to very tight and everything in between. Frame squareness, loose parts.
As for the Gcode I"m using a 1/4" 2-Flute up spiral bit 350im rapid speed/ 40im Cutting Feedrate.
I'm running out of things I can think of checking, I'm even questioning the rated size of the motors from CNCRP for the gantry.
