My solution is to  create a separate Gcode program for each different operation then run them consecutively after changing tools etc. (take care to use the same datum [X0,Y0] for each separate program).

Mach3 under Vista / Re: Unstable pulsing under Windows 7

« on: January 22, 2017, 03:18:02 PM »

Very very basically there is an incompatibility -  laptops use various power saving features and Mach3, when using the parallel port, places a high demand on processor and graphics. I have one old laptop that works beautifully using the parallel port and two newer laptops that just don't work well with pmcia parallel port cards. This situation was discovered way back by Artsoft - the result is that laptops are not supported for parallel port operation.

Please post your .xml file this will enable us to check your Mach3 settings.

each one of the gantry motors has its own driver but signals to the two drivers are parallel and come from the (Y) Chanel.

If you are still connecting it that way (not recommended) then maybe the Y Channel does not have sufficient voltage/current to drive two motor controllers correctly ?

Perhaps carefully check the connections and cable to that dodgy motor - could be a high resistance or even open circuit.

G-Code, CAD, and CAM discussions / Re: Trispokedovetiles: CNC code to cut tiles

« on: January 22, 2017, 03:34:04 AM »

Still thinking about this design for use as a jigsaw puzzle…

The puzzle would need to be round or hexagonal in shape to provide the maximum number of identical pieces but assuming the puzzle’s picture was printed both sides then each piece could have just one of 6 x the number of complete dovetiles as a possible position.

Just taking a snapshot of one dovetile bounded by a circle perhaps illustrates the possibility.

I think you were just lucky to get it working the first time. Laptops (docking station or not) are not recommended when using the parallel port. The recommended way  with Win7 and a laptop is to use an external motion controller (ESS, UC100, etc.).

You cannot drive your stepper motors directly from that board.
The Common Gnd, Step, Direction and Enable signals from each of the 5 axes are taken to suitable drivers and the stepper motors connected to them.
