I've got this 6090 router from Foshan Puruite.

The stepper motor driver cards have a 7-position DIP switch.
Wonder if anyone knows the switch mapping. Or...

I had a steps-skipping problem once, turned out to be a failed fan in the control box, and simple overheating. Something in the silicon wasn't making timing when too hot. Mercifully it was not a...

Added the leading and trailing % lines. Each is %CRLF specifically. Ran the operation sequence 3 times and it failed on the 3rd run. Same symptom, all moves executed but the spindle-off command...

Last few lines of the program are as follows. This was generated by DeskProto. This is the end of a waterline style 3D milling cut. A bunch of relative X-Y movements followed by a final absolute Z...

When it gets stuck it seems right at the M5 line. The entire cut is completed successfully, and the spindle still spinning.

The severity of hang is variable: (sometimes no failure), sometimes...

Ger21 and Roger,

Thanks for the suggestions. Turned off the path display and re-ran the program. Twice for good measure. First run terminated nominally. 2nd run terminated with all G code but...

Will try that. Had another instance today, and I can simply repeat the same cut with no work as a test. Does turning off the toolpath display mean editing the definition of the screen content? Or...

Confirming another instance of this. Machining sequence completes successfully. G-code display is stuck somewhere in the middle of the run. Spindle is still on, am able to turn it off manually. ...

Cause was a bad fan in the controller box. Indexer or driver IC was apparently overheating.

I have a gantry configuration router with stepper motors and USB RnRMotionController, running purchased and licensed Mach3 on a Windows 7 Thinkpad. Laptop has all the power management and screen...

I have a Chinese router CNCEST 6090 (Foshan Puruite). Has been working pretty well, cutting 3-D shapes with simultaneous X-Y-Z movements. Toolpaths generated by DeskProto, which I'm pretty happy...
