I’m sure a member of staff (Edwin? when he was still with the firm) answered a question about this issue and replied that it was a limitation of the simulation only and the toolpath would be generated correctly. I used your file with a huge stepdown to simplify the tool path and got this result:
… just showing the head. The simulation was showing exactly what you posted.
Incedentaly, the version of SMLuban 3.15.1 does not refresh the simulation image correctly after chaging the toolpath, I find that clicking the ‘eyball’ on the toolpath off and on fixes that problem.
Edwin was a whole lot more active on the forums than they are now that he left. I’m sure they’re just short handed but I do miss Edwin, much less communication between the users and Snapmaker since he left. It was already struggling…
I’ve seen reports of the rotary steps skipping or binding. Does anyone know if this is widespread? There’s been no communication from Snapmaker since they were reported. Unknown if it’s hardware or firmware/software related.
@Tracy do you know what’s going on with rotary modules? With all the reports of missed rotary steps or just flat out seizure of the rotary, is it prone to a manufacturing defect/s of the gear mechanism? What is the warranty period of the module? Probably already stated but I could’ve missed it. I haven’t been able to try mine yet, is it supposed to be able to turn freely by hand?
Sounds to me there is a multitude of issues, with some more hardware- and some more software related. I would expect the software ones to gradually disappear in the next FW updates (we also have come a long way since the original versions here), while the hardware will prrobably get multiple revisions (see print head cooling and drive gear); though you will probably not be entitled to the new hardware revisions automatically.
A few Rotary Module users have reported that they are facing a step missing issue on the rotary module. And we have received the defective ones. We are working on an analysis to confirm whether it is caused by the hardware or the firmware. As to the warranty period, it is one year long for the NEU and two years for the EU users. If the issue is caused by the hardware, we will arrange a replacement. Also, it should not be able to turn freely with your hand.
The rotary module will be available for Europe tomorrow.
For other regions the rotary module is already available. Now you can buy it at the official mall.
I don’t recall having ever seen anything but a 3 jaw. Can you share links? (or photos/screen grabs)
If you did they were probably just in prototype stage. SM has definitely been asked repeatedly (including many times in this thread alone) about the issues of using square stock with a 3 jaw. Their responses weren’t the most helpful. Definitely no indication of any plans for a 4 jaw.

@sdj544 I’m suspecting they’re going to release accessory chucks that you can buy. I’ve also seen someone that actually found chucks that aren’t made by Snapmaker that actually do fit, which tells me that Snapmaker did stick to one of the standardized methods so that’s good at least. I don’t remember who it was and what chucks he used but I do remember that he was Japanese.
Hi,
What do you mean by “is not recommended…”? It is not on the roadmap this feature? Is not recommended yet because Luban does not support it? When do you think it will be implemented?
Keep safe
@Ulopes Edwin is no longer with Snapmaker and Snapmaker has completely ignored the forum since he left. As for that feature, it honestly boils down to the fact that it would just make them have to do more work on Luban to make it useful for once and we all know they don’t give two shi** about actually making Luban functional. For 3d printing with the rotary it would be rather straight forward, just use a blank cylinder material as a print surface. Many other printers have actually done this and it works really well, but Snapmaker’s leveling sensor would also become useless unless the cylinder was metal, because for whatever reason they decided to use an induction sensor instead of an IR for the 2.0.
I am trying to cut some chess pieces and I am having severe layering/ striations in the cut. I can’t understand why I cannot get a smooth cut using a V-Groove 20 degree end mill from a STL that shows a nice smooth surface. The two pieces shown here are the same file except that one is using a 1.5mm stepdown and the other uses a 2.5mm stepdown (both have a .2mm stepover). Am I wrong to assume that when a pass goes from say 6 mm to 8.5 mm, the bit will raise or lower maybe .6 mm with each .2 mm pass to produce a smooth transition? Is this a limitation of the software or hardware or should I be changing my settings further. I mean I can change the stepdown to 0.5 and the stepover to .1 or something but it’s already taking 6 hours+ to cut this pretty simple piece and those settings would probably quadruple the time. Most particularly, I need to know if the stepdown is an absolute or relative adjustment? please help. Thanks in advance.
I have a question about the grip on the rotary module. I’m trying to use it to engrave on a metal cylinder like a tumbler. The aluminum keeps slipping as it’s metal against metal. I’ve tried a lot of different things to try and prevent it from slipping off but nothing seems to work. If you or anyone has any suggestions or possible solutions I would be really grateful.
