@catalin_ro hi there! I just managed to re program the vfd and this now works! It is awesome!

Thanks for all the help,
Alex

Oh yeah, the Hiwin rails that are "all the rage" are definitively the lowest end of the scale. (With the chinese clones not being on the scale at all).

However with the minimal forces involved with 3d printing they're a good alternative for smooth yet rigid linear motion without having your credit card curl up in a fetal position crying in the shower:P

If you trawl eBay you can find better brand rails used and they should have ample life left in a 3d print application, but its more often than not much much bigger rails.

That's what I was looking for, thanks for confirming that pendant works. Since you are experienced CNC machinist, have you got any pendant that is worth recommending? I wan't to avoid getting product with bad documentation and poor user base.

2.03RC4 is now released. Thanks @wilriker for the PR.

Damn, you guys are fast as lightning! Thanx

@mwinterm said in G30 / G31 issue with 2.03RC1:

I switch on the machine Home all Axis G10 L2 P1 -> Origin of workplace 1: X100.00 Y100.00 Z38.50 U0.00 V0.00 (from config-override.g) G10 P1 -> Tool 1 offsets: X0.00 Y 0.00 Z12.15 U0.00 V0.00 active/standby temperature(s): 0.0/0.0 (from config-override.g) G0 X0 Y0 move to the probing point I probe z-level using G30 I issue G0 Z0 to check if the tool moves to the probed level -> everything good (note the new probed level is different from the initial one) I issue again G10 L2 P1 -> Origin of workplace 1: X100.00 Y100.00 Z38.50 U0.00 V0.00. This result does not make sense to me. I would expect the Z-coordinate to be different according to the new probed level.
7 . I move to probe away to maximum Z-level using G53 G0 Z140 -> crash into the mechanical top level endstop After the crash the z-value displayed is Z113.65 which happens to be the maximum value possible with the initial calibration (113.65 = 140 -38.5+12.15)

Please can you try firmware 2.02RC3 and see if this issue is resolved. There have been fixes to handling workplace coordinate offsets between RC2 and RC3.

@wilriker said in Support for G38 for CNC users?:

@dc42 Only issue with M585 without my amendments is that it sets tool offsets at the end. It did you also include my flag that prevents this?

I will review this for RRF 3.

@bearer I got a chance of testing it today and the work coordinate system works perfectly, this is exactly what I was looking for. Thanks!

fusion post proc probably does either g28 or g54 g92 z0 at the start which can cause issues if your machine isn't set up right.

I'm on the same wavelength with Danal on this one! Unless specifically instructed through M120/M121, nothing should be saved/restored by default for maximum flexibility.

Of course, workplace related settings should be included in the push/pop support as some of the workplace settings might be temporarily changed for the needs of the macro.

@bearer said in CNC Coordinate Systems:

Is there currently any way to probe in directions other than Z? I see G38.x isnt supported, and G30 only takes x and y for locations to do the Z probe.

G38.x would be nice to have for CNC.

Look up M585 in the GCodes page of the wiki.

Many thanks for advise..

I've down loaded Fusion 360...

Now to trawl through the training vids

@bearer said in Duet 2 controlling a cnc spindle / VFD via pwm:

Could he use a 5V fan output if hes got one spare?

Yes, or a spare heater output.

@hpiz said in Yet another CNC improvement (Outside machine limits):

I just tried this with some manual gcode entry.
Starting at X-11
G1 X-50 F50
waited a few seconds until it was about a 1/4 done with the move
G4 P0 M5
Spindle stopped immediately.

That's expected. GCodes received over HTTP or from PanelDue are not synchronised. GCodes read from a streaming source are synchronised. So to test the synchronisation, put the M3/M4/M5/G1 commands in a print file or a macro file. Let me know if you find a sequence that doesn't work as expected.

Added to the wish list. But there is so much on the list for ReprapFirmware that I can't say when I will be working on PanelDueFirmware again.

thanks for the replies, it sounds like there isn't really an issue on the hardware side.
I've been learning Fusion360 and no issues there, just export the .nc file.
I'm also learning to use to Tormach CNC in our makerspace. These machines always come with their own software interfaces that do the same thing as the Duet webcontrol, but since that is printing-oriented, what would I use to manage the machine and jobs? Webcontrol can monitor progress, start and stop jobs, define tools and such, even jogging. But there are a lot of elements non relevant to cnc and cnc oriented items not in webcontrol (maybe setting the Duet to CNC mode also modifies the web interface to match?)

The problem is the "outside machine limits" message. In CNC mode, a movement command that commands movement outside the limits you have set in config.g will terminate the job, for safety reasons. So you need to identify that command in the GCode file, for example by executing lines from the file one at a time.

@mikethk Indeed, a relay or SSR are your only choices for that!

Thanks for the tip! I will take a look at that.

That is great news!
