Rotary 4th axis rollover on 360, G93, macros

T3P3Tony

@mrob ahh ok, so there is the option to change that behaviour seperate to an axis being rotational or linear

Sn (optional, supported in RRF 3.2beta3 and later) 0 = axes created in this command are treated as linear in feedrate calculations, 1 = axes created are treated as rotational in feedrate calculations. See section 2.1.2.5 of the NIST GCode standard for how the feedrate is interpreted. Default is S0 for linear axes and S1 for rotational axes (see the R parameter).

But you point about degrees/min vs mm/min makes sense none the less.

MRob

@t3p3tony Yeah exactly, even if you can include it, it is not very helpful.

So ahhh..... any thoughts on whether this could be built into RR at some point?

T3P3Tony

@mrob I have added it to the list of requests. I can't give a release target yet. Its very unlikely to be in 3.4.

MRob

@t3p3tony Amazing! Thank you! I'll keep an eager eye on this.

MRob

@t3p3tony Looking to start a new build soon, in the design phase at the moment, any thoughts on when these features might be implemented? Not expecting any sort of hard promises obviously, just a very rough eta would be useful! Like 3 months, 6 months etc.

T3P3Tony

@mrob I am hopeful (but can't guarantee it) that we will look at this as part of 3.5.

MRob

@t3p3tony That sounds great!! Although it does mean I need to ask when 3.5 final release is expected :).

T3P3Tony

@mrob while we try to work towards a major (3.N) stable release every 4 months or so, thus far it has pretty much always been longer than that (3.3 stable came out in June for example).

MRob

@t3p3tony Ah OK, so could be around 6 months then, I'll go UCCNC in the meanwhile.

@T3P3Tony Hey looking into this rotary axis roll over as well for my current application did this feature ever get implemented?

@maximyz3d there’s a GitHub issue for this here: https://github.com/Duet3D/RepRapFirmware/issues/780
It hasn’t been implemented yet.

T3P3 created this issue in Duet3D/RepRapFirmware

open Support configuring an axis as "continuous rotary" #780

@droftarts Thank you I will look into this GitHub link. Hopefully the feature is implemented soon. In the meantime, I will try to add the functionality so I can learn more about RepRap firmware.
