Position Error, can't get past it to run anything

Aggie.wes · September 7, 2025, 1:03am

I am repeatedly having an issue with maslow…. maybe hardware related? the belts all extend and retract as normal, seems very repeatable.

I made a cut a few weeks ago, everything went fine. I was even able to start this week and run part of my program without issue, but maslow got stuck with a location error mid-way through and i haven’t been able to get anywhere since. I was running v1.07 but i updated to 1.11 this week, hoping it would help, but no dice. Log file is below. Basically all I did was fix the z height after the ‘apply tension’ changed it for some reason and hit go. Any ideas where to start looking for a fix?

I had similar errors at one stage when it was running on a vertical frame. I have since gone to horizontal and I pulled the Maslow apart and sanded the belt axis and greased them with a mixture of petroleum grease and graphite. I have not seen this problem since. I think it was the excess friction on the belts causing the problem.

TimS · September 7, 2025, 3:58pm

Ian, isn’t petroleum bad to use on certain plastics? I thought I read that it can soften plastics. Is it safe to use on whatever plastic the spools are made from?

ian_ab · September 7, 2025, 8:33pm

While it works in the short term, it may degrade plastic over time. So do your research and decide for yourself. Some of the synthetic lubricants may have less long term downside effects.

bar · September 8, 2025, 7:10pm

Someone else reported a very similar issue over the weekend too so we might have a bug.

Is this with on a 4.0 or 4.1 setup?

If you use the arrow buttons to jog around does everything seem normal?

Aggie.wes · September 8, 2025, 9:45pm

4.1. Jogging, the machine moves a little strangely. It seems to almost do a little arc at the start of a linear movement, if that makes sense.

Just jogging it around on the table for a few hundred mm has caused a similar error as well.

bar · September 9, 2025, 6:03pm

How does the tension in the belts feel? This sounds to me like the machine might be struggling against too much tension.

Does it sound like the motors are struggling at all?

Aggie.wes · September 9, 2025, 7:32pm

I don’t hear the motors struggling, and I’ve been able to retract all successfully with the retraction force set at 1500.

If anything, I’ve noticed one of the 3 belts going more slack (whichever anchor point I’m moving away from) than I feel like it should be.

ian_ab · September 9, 2025, 8:19pm

This sounds a bit like one or more of the belts is binding. Try setting the retraction force really low 200 and doing multiple retract extends until all of the belts are out as far as they will go, then reset the retraction force and pull all the belts back in, maintaining a little resistance pressure to ensure they pack down properly. When you have the belts full extended it wouldn’t hurt to blow them out with an air pressure hose if you have one to get rid of any sawdust etc

Aggie.wes · September 10, 2025, 12:11am

I recalibrated on the past 2 days, and I forgot to set the frame size to something reasonable first, so I pulled out like 2x as much belt as I needed during that process, so I think we’re good there.

bar · September 10, 2025, 2:00am

So the issue persisted across multiple calibrations? It seems to always be moving in that weird way?

Can you get a video of it? I’m stumped

Aggie.wes · September 10, 2025, 2:55am

Yeah, I just got home from out of town, I’ll try to get a video tomorrow.

Aggie.wes · September 14, 2025, 6:43pm

@bar video linked. honestly it moves like normal, acts like it’s about to cut, and then i get the position error. VIDEO

not sure if you can see it in the video, but after the error, the lights on the maslow turns red and flashes blue. then it disconnects from my computer and won’t reconnect until a power reset.

And here’s the latest log file, basically same as the first. it is consistently that same BL arm, but it doesn’t act strangely, i don’t have any issue with retract, and the belt seems to go to the same length every time…

The log below, I jogged the machine around for a bit to see if i could cause the error from that, no issues, but the instant i hit ‘start’ on a program, the error shows up and the machine stops:

Hmmm yeah that is super strange. We had a bug that was similar but it was causing issues when moving to where it was going to start cutting, and this seems to be an issue once it has already gotten to where it is going to start cutting.

Can you post the gcode? I’ll try running it and see if the same thing happens for me.

Can you give this gcode a try and see if you have the same issue with this test file? No need to actually be cutting

So i had to hit ‘stop’ before your program got to the end of the jog, since i didn’t reset my home before i hit ‘go’ and it’s a bigger “Hello World” than I thought, lol. Regardless, the two trailing belts started spooling out pretty significantly to where I would have hit ‘stop’ anyway. VIDEO

Look like I got it working. I was having issues with earlier firmware, so I upgraded to 1.10 and figured I’d do a calibration with the new method and basically the 5x5 grid wasn’t good enough. I got values that were up to 100mm different from when I previously ran calibration on a 7x7 grid.

So basically I plugged those values in, upgraded to 1.11.2 and now everything seems to be working again.
