Mach4 General Discussion / M command not doing its job

« Last post by Bill Phillips on October 17, 2025, 11:37:28 AM »

I am brand new to Mach 4. I have been using a shopbot machine. I am now using an Avid machine. I am trying to set up a relay to start the vacuum table fans. The user guide says that M8 turns on relay 1 and M7 turns on relay 2. I put those M commands in the file but they don't turn on the receptacle under the control box.

German / Stop Spindle. Wait for Cycle Start, komisches Verhalten

« Last post by martin2day on October 16, 2025, 03:41:57 PM »

Hallo zusammen,

ich bin der Martin und ich habe mich hier in dem Forum angemeldet, weil ich eine Fräse mit Mach3 Steuerung erworben habe.
Bisher hatte ich nur das Vergnügen Industriesteuerungen und zu Hause mit EstelCam bzw. einer Software von Knuth.
CNC Erfahrung ist sozusagen vorhanden.

Ich habe seit alles gut verstanden und mich in die Software eingearbeitet.
Homing, Softlimits und auch kurze Fräsprogramme abarbeiten funktioniert super.

Jetzt habe ich aber mitbekommen, dass er bei einem Werkzeugwechsel nicht anhält sondern direkt weiter macht.
Im Handbuch habe ich die passende Option schnell gefunden.
Tool Change: von "Ignore Tool Change" auf "Stop Spindle. Wait for Cycle Start" gestellt.

Der Stopp funktioniert jetzt super, aber: Sobald ich dann den Cycle Start drücke rauscht er mit mit X und Y direkt ins Minus obwohl er im Programm noch "T04 M06" steht... das ist vollkommen unlogisch für mich
Hier mein Programmauszug:

O0001
N1 G21
N2 (6mm ...)
N3 G91 G28 X0 Y0 Z0
N4 T04 M06
N5 S10000 M03
N6 G90 G54 G00 X1.09 Y-41.687

Ich habe schon bissl im Netz geschaut was es sein könnte. Unter Settings Alt6 sind recht nur 0.000 eingetragen.
Habt ihr einen Tipp für mich was das sein kann und warum er direkt ins Minus rauscht obwohl er noch auf Zeile N4 steht?

Vielen Dank euch.
Gruß Martin

Mach4 General Discussion / Re: Mach 4 default min spindle speed change?

« Last post by Steve Stallings on October 16, 2025, 02:07:05 PM »

Check the settings in the chart under Config>Control and select the Spindle tab.

A setting such as 8000 minimum is common for 24000 RPM spindles because that is the speed below which the motor will have too little torque to be useful and trying to cut at low speed may cause the motor to overheat, especially if it is not water cooled.

Mach4 General Discussion / Mach 4 default min spindle speed change?

« Last post by jamescnc on October 16, 2025, 01:45:32 PM »

Hi, I'm using mach 4 and im trying to set up my rapid change atc, I can control spindle speed with the vfd to be around 1500-2000 easily but on mach 4 it seems my  minimum  spindle speed is set to 8000rpm, I can turn it on and use the override to increase rpm but I cant go lower. even with the command M3 S2000 it still wont go below 8000, where can I find the setting to change this? I have ess installed as well.
Any help would be appreciated, this is the last step I need to figure out.

Thanks

Sounds like a comms or feedback glitch between Mach3 and the CSMIO/IP-S. Try checking probe wiring and grounding, updating the CSMIO plugin/firmware, and lowering PID gains. Also test a manual probe from MDI to see if it’s motion-related. A plugin reinstall often clears this up.

Hi Eric,thanks for the quick reply.
That disappointing to hear. I thought there would be lots of interest in this. I know I would have put it to good use as I'm pretty slow at designing on fusion 360 or inkscape lol. Well if you ever get back to it I would sure like to be one of tge first to utilize it.
Thank you and have a great day

Hi Bruce,

Thanks for your interest.  I got CamCopy M4 to a working prototype stage for testing.  However due to lack of interest from Mach4 users (ie, you are the only reply in over 2 years), I have ceased working on this version of my camera tracing program.
