General Mach Discussion / Lost steps after reset or e-stop
« on: January 06, 2021, 08:16:07 AM »
Hello, i'm new to Mach3 and i have the following problem: if i stop my milling machine on rapid movement with e-stop or reset, it stops very abrupt and sometimes the steppers are loosing steps (0.1-1 mm!). If i hit the reset button during slow speed, it stops without loosing steps. The spindle speed and acceleration settings seems to be ok during milling. The machine is ok and looses never steps. Only on e-stop/reset during fast speed. Is there a way to set the "emergency stop" acceleration?

G-Code, CAD, and CAM discussions / Touch probe with false values
« on: June 18, 2020, 10:28:01 AM »
Hi,

I have a working tool length sensor, but I cannot manage programming with the G code.
A want to use a separate program that should be called up if necessary, drive the tool over the permanently mounted sensor and slowly lower and set Z to zero. This works beautifully, but the zero point is sometimes incorrect.
The tool moves to 80mm, as soon as the program is finished, the Z value jumps from 80 to 82.16.
But why? All tool lengths are at 0.

Code: [Select]
N0010 (Filename: ToolChange.ngc)
N0020 (Post processor: Mach3.scpost)
N0040 G21 (Units: Metric)
N0050 G40
N0060 G90 F1000
N0100 G53 X35 Y58 (machinencoordinates for sensorposition)
N0120 (T201 M06)
N0130 (G43 H201)
N0140 G31 Z-300 F500
N0150 G92 Z45.9 (height probe)
N0190 G0 Z80 (up)
N0340 M05 M30

Calling the right or another tool doesn't change anything.
If I continue milling in the sam program, it always fits.
If i start another program, I have this offset. Any ideas?

German / Hilfe für Werkzeuglängensensor 2
« on: June 17, 2020, 03:25:04 PM »
Hallo,

ich habe einen funktionierenden Werkzeuglängensensor, komme aber mit der Programmierung per G-Code nicht klar.
Ein eigenes Programm soll bei Bedarf aufgerufen werden, das Werkzeug über den fest montierten Sensor fahren und sich langsam absenken, nullen und wieder hoch fahren. Das funktioniert wunderschön, allerdings stimmt der Nullpunkt gelegentlich nicht. Dieser verschiebt sich um einen krummen Wert, aktuell 2,16 mm, sobald das Programm beendet ist.
Im Programm wird auf 80mm angehoben, sobald das Programm fertig ist, springt der Z-Wert von 80 auf 82,16.
Aber wieso? Alle Werkzeuglängen sind auf 0.

Code: [Select]
N0010 (Filename: ToolChange.ngc)
N0020 (Post processor: Mach3.scpost)
N0040 G21 (Units: Metric)
N0050 G40
N0060 G90 F1000
N0100 G53 X35 Y58 (Maschinenkoordinaten für Sensor)
N0120 (T201 M06)
N0130 (G43 H201)
N0140 G31 Z-300 F500
N0150 G92 Z45.9 (Auslösehöhe Tastkopf)
N0190 G0 Z80 (hoch)
N0340 M05 M30

Das Aufrufen des passenden Werkzeugs ändert auch nichts.
Wenn ich danach gleich weiterfräse, dann passt das immer.
Ich möchte aber ein anderes Programm starten, habe aber dann diesen Versatz. Wer hat eine Idee?
