@phaedrux I actually went through the delta calibration guide and copied the M665 and M666 params directly. Is M500 something that should be run after an auto calibration?

@jay_s_uk Yeah, I need to change something. Getting weird effects with my prints that I've never had in the past. The calibrations continue.

Here is config-override.g:

G10 L2 P8 X0.00 Y0.00 Z0.00
G10 L2 P9 X0.00 Y0.00 Z0.00

@phaedrux The M208 is commented out because I couldn't get the right behavior with it. I tried making it negative as well, which just showed the problems with the print gcode, trying to print at Z=.2, which doesn't really work. Didn't know that about the height map, it was in the original code that came with the printer. I'll take it out. In general, I'm not in any hurry when I print, so I usually do run calibrations before every major print, if only by running macros. Putting it directly into the slicer is a great idea. Incidentally, here is the macro I usually run to create a mesh of the bed:

I'm running a print right now and can post the M122 and M98 when it's done. Thanks!

@phaedrux I'm not sure it's the best solution, but I did find a solution: M290, in the preamble for every print. Seems to have solved all of the issues I was seeing. I can still post the files, if there is still interest. Thanks.

I'm having issues after upgrading my firmware, getting sane values for minimum Z. If I set minimum Z using M208 to say, 1.2mm (M208 Z1.2 S1), it solves the problem of the head being too close to properly extrude. However, I end up having problems with the slicer (Cura), with layers getting mashed together and making a mess, when Cura tries to create something like a brim with a height of .2. If I take out the M208, the printer will actually try printing at Z = .2, which causes a different problem. I've never had this problem before and am not sure how to fix it, either in firmware/gcode or in Cura settings somehow. Printer is a Rostock Max v4 with Duet 2 Wifi, running RRF 3.3. My apologies if I'm just being a noob.

@phaedrux Oh, sorry. The missing tool problem was a direct result of missing the M584, required in the newer firmware. Again, thanks for the help.

@daveman1010220 After combing through the differences from the original rmax v4 gcode and the generated gcode from the link above, I found some subtle differences and finally have a working "first probe" calibration (again). Thanks for the help, everyone.

@phaedrux Thanks for the help! I've gotten past the "no tools" problem. Now I'm trying to run a "first probe" macro and am running into issues with the Z descent not reaching the bed. It stops mid-way to the bed and attempts to probe, which then fails because it's not even close to the bed. I've set the right parameters for my printer in:

M665 L340.500:340.500:340.500 R144.000 H350.000 B135.0 X0.000 Y0.000 Z0.000

It's as if no matter what I tell it the printer dimensions are, I get ignored. Any thoughts on how to fix this? Do I need to compile a custom firmware binary? Thanks!

Hello. I upgraded the firmware on my Rostock Max v4 with Duet2 Wifi, from 2.x firmware to 3.0, then to the latest 3.3 firmware. I then tried to use the printer and discovered I had broken the world. I've read a lot of the docs at this point on updating configs and have made many edits to my gcode, but I'm now stuck. The printer reports that it has no tools, which causes many secondary error messages/failures. This is my first time on this forum, so hopefully sharing my configs here is ok. Any ideas/help are greatly appreciated.
