Snapmaker 2.0 rotary -frame works but start does nothing

I have Snapmaker 2.0 working fine on the 3axis setup. - Device set as Marlin

I am trying to get the rotary module setup and have been working on and off for weeks as I continuously hit different roadblocks and seem to get to a dead end with it and give up.
At this point the rotary is setup as Marlin Snapmaker- the rotary is enabled and has B axis on. When I do the test everything moves as it should on all axis.
I have a test engrave to try and setup the origin point and have the offset and crosshair enabled and get everything lined up.
I run the frame and the rotary and Y axis drive correctly to frame.
Now I try and hit start to begin the job and it sits doing nothing on the machine but has busy with the timer counting in the lightburn software. It stays like this until I have to stop it

Any help please before I give up on this again

No one got any idea on this?
Possibly one snapmaker going on the market… I cant use it for what I want

Draw a square 50mm side.
Save and post here the GCode for us to have a look.

50mm sq test Framing works Start does nothing SM2 IR rotary.gc (2.4 KB)

Hi, I have just got back home and to the machine. Attached it the Gcode

The best source is from @Skreelink, check the following guides:

and report back.

I have been through these to setup.
My non rotary engraves work fine.
As soon as I try the rotary module everything seems to function but it just won’t begin the engraving.

Im unsure how it can engrave on a 2D surface with no issues but as soon as I try to enable rotary there’s nothing.
The axis are all enabled and functions as the framing works correctly.

Did you notice anything with the gcode?

Thanks for trying to help

Ive gone through a fresh setup following the above again and still get the same issues. Gcode attached

I have noticed once i click start the machine doesnt even begin by driving to the home position

Can you run please a project that works in flat mode and post the GCode to compare the output?

Flat 20mm sq test.gc (371 Bytes)

I have just run this one successfully.
Still no joy with the rotary

The rotary is only a line the flat is a square

  • It seems that they´re using GRBL or Marlin and not the Snapmaker profile.

  • Remove the thumbnail line from the rotary GCode.

  • Export your devices to a safe place then duplicate (2) them.

  • Edit one duplicate and set it as GRBL .

  • Edit the other and set it as generic Marlin

Try again.

Couple of questions on the notes above

  • It seems that they´re using GRBL or Marlin and not the Snapmaker profile.-> What is using GRBL or Marlin?
  • The Marlin doesnt enable the B axis only A, for rotatry I need B axis in the snapmaker Marlin
  • Remove the thumbnail line from the rotary GCode. ->What is the thumbnail line in the rotary Gcode?
    thanks again

  • 1 . Do a duplicate of the device profile then click Edit:

    In the next window you can change the controller type from SnapMaker (Marlin) to generic Marlin or GRBL.

  • 2 . You have to install Notepad++ post edit the GCode and change all instances of A to B.
  • 3 . When you open the saved GCode you have to delete the line that begins with the word “thumbnail” that’s known to hang the controller.

I don´t have the machine so I can´t help with 100% certainty but try the above and report back.

Ok so I am getting somewhere now.
I left the machine in snapmaker marlin and saved the gcode the same as the one I had sent you .
I checked the Gcode in notepad++ and did see the thumbnail line generated in there.
I deleted that and ran the Gcode. My machine did spool up the laser fan and moved to the home position and appeared to run the job.
The coordinates were way high and to the far left of the job but at lease I have progressed and got the laser to move.
now to find out about the job origin to get it in the correct position.
I use user origin and have the job origin and the bottom left. Maybe I have to change that
Definitely progress on this step though. Thanks

Export your profile .lbdev and post here.
For rotary work try Start From Current Position.

I did do current position and some testing earlier today. It was burning slightly to the right on the X axis. almost like the offset for the red alignment laser wasnt working.
It did do one in the correct position but I hadnt entered the correct object diameter so the x line on the cup wasnt a correct square. When I tried again it was off to the right of centre again.
I am away for a couple of weeks at work again now. I will continue testing once I get back
