I do recall getting the same thing sometimes, but i never really bothered with why it happens, it is a sim and i use it only to check the gcode sometimes, not for anything important.
If you want to test on a real machine but with no machine attached, use the parallel port configs, so will work even with no parallel port, but it is a real machine so nothing is simulated. You will have to use immediate homing for it though.

Thanks everyone for the support.
Yes, I know, so where can I change the value in the source code?

Perhaps someone typed " " instead of "", or perhaps it's an intentional design to ensure an empty filename is impossible.

Hmm...

What does "probe height" mean.

Same as: linuxcnc.langdonstaab.ca/42-deutsch/57850-rack-atc

Could you provide us with some more info regarding the machine and what you hope to acheive?

The ideal way would be to have 2 sets of step/dir signals and 2 Y home switches so
any gantry racking can be corrected every time the machine is homed.

Whether one step/dir output can drive 2 motor drive inputs depends on the current
requirements of those inputs, but in general I would suggest the separate drive/separate
home switch system.

I'm in the process of upgrading my DIY router mill to include dual Y axis steppers. The current configuration uses a single Y stepper to move a rather long axis (~ 44 in) on which the X axis rides to provide X/Y motion for cutting.  However, on long, fast moves I sometime notice slight cogging.

I have an extra stepper and Microstepper that matches the current Y Stepper-Microstepper combination that I would like to incorporate to minimize cogging.

The machine uses a MESA 7i76u 5 axis control board. My question is, will the MESA 7i76u provide sufficient direction and step current to drive two Microstepper drives so that both get their signals at the exact same time? Or, do I need to configure separate sections of my HAL and configuration files to drive each driver separately and if so, how would I go about the configuration?

I did find an old post on the subject of two steppers for an axis, but it was for a rather old version of LCNC.  I guessing that 2.9.4 may have a more straight forward approach to configure dual axis drives.

Kind regards,

Thanks for your reply tommylight. Sorry if this sounds stupid but I selected each axis (X, Y, Z) and click the +/- buttons to move it in that direction, but it still doesn't seem like Home All works. It only seems to home the y axis (so j = 1).

Im still getting errors for j = 0 and j = 2

Simulated switches so you have to move all axis to be able to home again.

I think I might of taken a pic of mine but no originally it was rbobey1989

I'm having trouble understanding why my "axis" simulation is getting "Cannot home while shared home switch is closed". This happens once I click "Home All" twice. I'm wondering if I have something setup incorrectly.

My end goal is to be able to do this via python. I have attached my current python code (which I don't think is the issue) and I get the same issue.

Thanks

dachte eher so:)

Erledigt.

Ich kann das leider über den link irgendwie nicht finden wie ich dich kontaktieren kann bzw ist die mail rinfach nur @rotarysmp ?

The difference in test 1 is -22.036mm.

In test 2 its +22.175mm.

Sign does matter.

Servus Tom,
Es gibt kein DM funktion hier im Forum. Auf meine YT channel gibt es meine Email adresse.

Ich kann dir meine Retrofit Notizen zukommenlassen.

Bei meine 400E waren 2 Kannalle der Exe Karte hin. Ich habe 2x 602D EXE's eingesetzt. Die haben zwei vorteilen.
- Brauchen lediglich 5VDC. Der Original 3x Kanal EXE braucht 5VDC und 12VDC.
- Differential Signal, statt bei der 3x Kanal lediglich Single. Obwohl Heindhains Kabel und Schirmung ist so Hochwertig dass es wahrscheinlich wenig unterschied macht.
Mann muss nur aufpassen,. Machen 602D sind 1µm, andere 5µm output. Heindenhains Modelnummerierung sind nicht sehr durchschaubar. Ich glaube 610 EXE sind Resolution auswahlbar.

Ich haben auf meine Schaublin eine etwas erweiterte Bedienpult mit Tastatur, buttons, encoders etc gemacht. Alles ist an der 7i73 angeschlossen, ausgenommen Tastatur (USB) und E-Stop (Hard wired).


MESA 7i97 für die Achsen, Encoders und Spindel Servo
Mesa 7184 I/O
Mesa 7i73 Bedienpult. 
Tom's handwheel (Pendant.) 
talla83.de/Tshw.html (Peter's website.) Die ZIP file für die Boards kann mann selbe an  JLCPCB herstellen lassen. Sonst Frag Peter ob er einen fertigen Verkauft.
