Mach4 Toolbox / question

« on: August 15, 2020, 03:16:07 PM »

Can a Mach3 brain be used on Mach4? We have a brain controlling the spindle.
I've attached the existing file.
Thank you

I found the easiest way to solve this problem is to edit the g-code and just add an S0 command after the M5 command.
There is also a field in the general setup that you can add an S0 command on every E-Stop. That will set the speed to 0 whenever there is an E-Stop and the program has not reached the S0 command.

Just as a safety precaution. If Mach is running and an inadvertent M3 command is issued, or if the spindle start button is activated the spindle will turn at the previous rate.

CamBam generates the G-code with the m3 S commands. Other than adding a footer to set M5 S0 is there a setting in Mach to tell it to set S to 0 when the M5 command is initiated?

Brains Development / Mach holding spindle speed

« on: December 05, 2017, 07:46:51 PM »

Hello All,
I'm running the brain attached with a Hitachi WJ200. Spindle is controllable with M3 and M5 commands and the speed is controllable
with the S.... Command.
The Problem:
If the spindle is turned on and a speed is set with the M3 S12000 command all is well and the program runs.
Enter the M5 command at the end of the program and the spindle stops, the run light on the VFD goes out and all is well.....UNTIL
If you enter a M3 command on the command line without the S following, the spindle will turn on and go back to the previous 12000 rpm number.
It appears Mach is holding on to that number, not the brain and not Modbus. Checking the registers on the modbus yields a 0 rpm.

Is there a setting on Mach that I am missing?? Why is Mach holding that speed?

The only work around I have found it to include S0 after the M5 command in the running program.

Any Ideas???
Thanks

I have the same issue. I have a routine to cut keyholes in wood. I have a jig that works for any size up to 24x24 and after the operation the program tells the machine to move away to a safe location based on the size of the work piece. At the beginning of the g-code, the m3 s1 command turns the spindle on but at the end of the program the spindle shuts off even though there is no m5 command.
Does Mach inherently shut the spindle down at the end of the g-code and what triggers it??
Thanks

General Mach Discussion / Huanyang VFD fluctuating rpm

« on: November 29, 2016, 09:04:10 PM »

HELLO,
I have the CNC Router Parts CRP800 control box driving a 2.2kw Huanyang vfd and spindle.
M3 commands work and the rpms match the VFD and verified with an RPM laser meter.
The problem is that there is a 400 rpm fluctuation up and down which makes the spindle unusable.
If I put the VFD setting back to control it with it's on board panel, the rpm is rock steady and I have used it this way for the past 2 years.
Voltage checked at the VFD with a digital volt meter "appears" to be steady but I'm not sure this is a valid test.
Any help would be greatly appreciated.
Thanks

VB and the development of wizards / tool path display in VB

« on: December 04, 2015, 09:01:04 PM »

I have this simple VB program that just routs keyholes in wood.
It works perfectly from a new screen I made for Mach.
Is there a way to show the toolpath?
Thanks
