Heidenhain TNC620

[m.van.hameren]

Hi there,

Nice to have a forum like this.

I'm new to Autodesk Fusion 360 cam and have my doubts about the Heidenhain generic postprocessor.

I'm familiair with cam, used HyperMill imbedded in SolidWorks for my previous machine, an old Deckel FP4nc with Dialog 3.

Recently we switched to a new machine with Heidenhain TNC620 and I need a good working postprocessor with it.

Anyone here got experience with this combination and can help me out?

Thanx in advance, Mark.

Pretty sure the generic Heidenhain should be good.

What is it you are worried about?

[m.van.hameren]

Thanx for your reply Laurens,

A very simple contour, 4 passes in Z-axis.

Just look what happens in line 9 and line 13, nobody approaches Z=0 (top of stock) with Fmax, that's just rediculous!!

In line 15 it moves X and Y axis to the entrancepoint while Z=0??? and in line 16 it moves Z axis to +15 again.

Don't think it's very logical....but perhaps I'm missing something overhere.

Thanx for your time and efford,

Mark.

You missed the M91 at the end of the line, so that line:

L Z+0 R0 FMAX M91

will move the Z-axis to the very upper limit in machine coordinates.

[Laurens-3DTechDraw]

Hi Mark,

That is in M91. (Machine Zero coordinates.)

Usually this in the top of your Z-axis. In case the machine builder was an ass and put it at the bottom of the Z-axis you will probably have to use M91, which can be set on the control.

I attached a part of the manual.

So actually those moves are for extra safety, since they are done with the Z-axis on their maximum.

[m.van.hameren]

Again thanks for reply,

That might be, I can't find M91 in my list of m-codes.......and the machine does nothing with it, it just goes on crash course.

Mark.

[Laurens-3DTechDraw]

You sure you have a TNC620 and M91 does nothing?

I mean it could go to the machine's zero point. And you could place that anywhere in the machine's workspace in theory. 

But it should always have an effect putting M91 in the line.

What machine are you trying this on?

[m.van.hameren]

Abene VHF 320,

Have to check it, but my zeropoint in Z-axis is the top of my stock, so yes it goes there with FMax.

But that is not what you want offcourse...

[Laurens-3DTechDraw]

Do you have any example programs?

[m.van.hameren]

EDIT: Found some more M code's now in the Heidenhain manual. I only checked the Abene short manual....

Same situation is with Heidenhein 415b.

Line with M91 is not correct, than i use L Z+15 R0 FMAX (on example), and works perfect.

[Anonymous]

That line is a safety move to the Machine z 0 

I'm using the custom heidenhain post on our iTNC540, since our machines 0 is in the top of our machine the line is fine (for M91).

For our iTNC425 I had to modify the line so it went to Z-1 because the machines z0 for M91 is beyond the limit switch.

I don't really understand why it does not work for you..  unless the machine 0 is somewhere in a weird spot.

What happens when you manually run the L Z0 R0 FMAX M91? Where is it going?

You also have an option in the post to use M92 instead of the M91.

Maybe check where the Z0 M92 is..  and if that is a safe spot use that one.
