I am using Vortex-A_axis-Grbl.pp (created Tuesday, April 23, 2024, 9:15:48 AM) loaded into vCarve Desktop. Shows correctly when I save a toolpath.
@mhforbes That’s the one.
For what it’s worth, have never before now needed to change any settings in gSender. So if someone thinks I should reset to defaults, I am all good with that. I do have the SLB and vortex installed now.
Partial rotation would be due to the last-second changing of the microstepping to 1/32 on the SLB.
The formula for rotation is:
So you’ll need to change your rotary axis value (be it Y for hijack or A for true 4-axis)
2.469 / (1 / 32) = 79.008
You’ll notice this is approximately 4 times the current value (19.753) - which would explain why you’re seeing a quarter turn instead of a full rotation.
This value would go in $101 (Y-hijack) if you’re using/in rotary mode or $103 (A) if you’re using true 4-axis.
@KGN I’ve not used the Vortex in a while, Kevin. When I did, 19.753 worked fine. Can I take it from your post that this is no longer the correct setting and we should go with 79.008?
Tks
I’ve updated and am testing. Looks much better.
This is only on the SLB. We’ll be updating defaults with the next firmware release.
@KGN Tks much Kevin.
@mhforbes I apologize for the bad advice, Morris. I was going on past experience when I had the same issue as you. Clearly, I was out of date. That will teach me to think that I know what I’m talking about. 
I have nothing but admiration for you and the team at Sienci. This is all good.
@mhforbes I appreciate that. I’ll bask in their glory, but just so you know, I’m not one of the team at Sienci. I’m just your not so humble forum moderator. Please post your successful chess piece.
If it makes you feel better, this just came up Monday and was the first instance of “oopsie” when it came to the new microstepping value on release. Hopefully after seeing the math the “why” makes sense - along with most of your beta testing being on the old microstepping value hence why the general A steps/mm working before.
@KGN Thanks much, Kevin. The math does make sense. I appreciate the morale boost.
Test piece in pine. Scaled down, since I don’t keep 2 inch pine laying around. Worked with the SLB and the new settings.

@mhforbes Looking good, Morris. Tks for posting.
@mhforbes Very nice. You should post these in the Show Off category.
I’ll do that after I finish a king in each of mesquite, maple, cherry, and walnut. Working on them now. They take a while, but easy enough. Building sets for two chess boards to donate to a church auction.

Hey there! Your chess pieces look amazing! I’ve never tried carving them myself, but it looks like quite a skill. Have you considered adjusting the speed or depth of your final pass to maintain the sharpness of the crown? And hey, I’m a big fan of chess, too! I could play it all day. But sometimes, when I need to unwind a bit, I switch over to spider solitaire. It’s a great way to relax and still keep the mind engaged! Give it a try!
