General Discussion / Smithy 1240 Linux to Mach3
« on: November 14, 2015, 10:54:20 PM »
We would very much appreciate your assistance in getting our Smithy 1240 running with Mach3. Briefly, the spindle does not operate correctly and we seek advice from someone with more expertise. I am having a time trying to learn all the technical aspects of the electronics and what the parameters should be in the Mach3 software. I think we are close but just do not have the technical knowledge to get the project finished.
The X,Y and Z axes seem to be working fine after using the auto setup found in Mach3. The limit switches and homing are working as expected. The central problem is controlling the spindle. An m3 or m4 code both result in forward rotation of the spindle. The actual and commanded speed (using an s command in a program or in the MDI tab) of the spindle is different. The maximum speed should be 4000 rpm and we are producing about 3500 or less. The worksheet from the PMDX website and a note on a similar thread really helped. We removed the linearity.dat file from about four places in the Mach3.
When we purchased the machine the original EZTROL system was abandoned in favor of a desktop computer using the printer port and a cable to the PMDX-110. The computer had a dual boot Windows XP and Ubuntu operating system with LinuxCNC running the mill. A prior owner loaded Windows XP on the computer along with Mach3. We gave Mach a quick try but did not get good results. We used LinuxCNC to run the mill for a couple of years and due to a litany little problems with LunuxCNC we decided to shift to Mach3 after a fresh installation of Windows XP.

Connections at the C300 from the PMCX-110
GND two wires violate and orange
FWD Black wire
REV Red wire
VC Nondescript color
Cable colors change due to loom make up leading from C 300 to PMDX-110. We can trace if necessary.
Wires and the switch settings at PMDX-110 can be seen in the attached photo of the board.
