Tension seemed to be alright, I recall Maslow printing message that current in one of the motors exceeded threshold, maybe one of the motors don’t have enough power to pull Maslow up.
As a one step of debugging process, we want to lay down the frame to make it horizontal. Run calibration, and then see if it’s still an issue

From what I recall, 15 degrees angle is minimal angle for Maslow, and you @bar have 20 degrees angle on your frame, so that does ring some bell in my mind

That 15 degrees I believe was for the OG Maslows, not the M4.
After doing several tests I would recommend 20 degrees as the absolute minimum; I found that 15 degrees is just not enough.
If you can, go for something between 22-25 degrees.

Building The Maslow 4 Frame — Maslow I think it’s good Idea to update docs here, cause it’s still 15 degrees angle here.

@bar After tilting the frame to 28-29 degrees, I think we got it, thanks for support, and let’s hope that we won’t have more problems

Excellent! I am glad to hear it!
I was having many issues with the wifi (AP) connection, I was using a win11 portable, lately I tried with a Raspberry Pi 3 and all the problems are gone.

After longer tests here is our experience: machine has failed to perform even the most basic cutting operations in our case. We had high hopes for this machine, but the issues we’ve encountered make it virtually unusable for precise work.
- Cutting Accuracy Issues
Straight lines are simply not straight. When attempting to cut a rectangular panel of 2500x1250 mm, the dimensions are off by several percent. This is unacceptable for any work requiring precision.
The machine’s cut paths are inconsistent. Instead of clean edges, we get cuts that deviate from the expected path, with irregular distortions appearing along the way.
The corners of our rectangular cuts are not precise – they appear to be rounded or shaved off rather than forming a sharp 90-degree angle.
In some cases, the machine doesn’t follow the programmed toolpath and instead carves unintended decorative patterns into the material, rendering it unusable.
- Wi-Fi Connectivity Issues
We’ve encountered continuous connectivity issues with the Wi-Fi module, regardless of whether we configure it as an access point or a client. The machine frequently disconnects, making remote operation unreliable and frustrating.
We have tested multiple configurations and network setups, but the problem persists across all attempts. This significantly hinders workflow and makes it difficult to execute longer cutting jobs reliably.
We have attempted calibrating the machine multiple times, double-checking our G-code files, and using different firmware/software configurations, yet none of these steps have resolved the issues.
At first, it seemed like the Wi-Fi connectivity had improved, but unfortunately, this was only temporary. The same problems returned, making remote operation unreliable once again.
At this point, we are deeply frustrated and disappointed. We have invested significant time and effort into troubleshooting and upgrading components, but the Maslow CNC simply does not deliver the precision or reliability we need.
Regretfully, we are now considering giving up on this machine altogether. It seems that despite all our attempts, the Maslow CNC is not capable of meeting our requirements. If anyone has a last-ditch solution or has managed to overcome similar problems, we’d love to hear it. Otherwise, this may be the end of the road for us with this CNC.

Switching from a wooden vertical frame to horizontal floor was a big improvement for me.
I just switched to firmware 1.02. Brought back from brink of death. Further cuts will tell if reliability is truly improved. Made one cut without issue. Hadn’t had that happen in a very long time.
I tend to avoid linear cuts. I have a track saw for those. Maslow excels at curves.
I have experienced maximum frustration at times, but keep coming back since nothing competes with this. Similar tools sell for way more and take space I don’t want to give up.

In our case horizontal configuration was terrible, it was much worse than vertical
From your images, it seems that the outer corners of the cut is very close to the anchor point on the frame.
I’m not sure you can expect to get a precise cut that far out in the corners/edges if that is the case.
For cutting 2440x1224 material, I have a framesize of 4500mm horizontal, and 3000mm vertical.
My guess, when it comes to the wobbly lines in your pictures, is that the top left belt does not have enough power to keep the Maslows own weight from pulling it down when running it that high.
How much of your material is in the white zone if you put in the measures here:
Maslow frame - Calculator
This is how it looks with my measures, and I have no issues with wobbly lines so far.
I have my frame tilted at about 50 degrees because of roof height if I remember correctly.
I am running with a 12000rpm spindle, 3.175mm 1flute upcut bit at a feedrate of 600 - 1200 mm/m.
It seems to be pretty precise for drilling, pockets and cutting so far.
Any issue I have had so far has been due to bugs in the newest releases, but I have not tried to run any jobs while experiencing bugs.
The above piece was made in Fusion360.
I made 2 of these, and they are very precise.
Each piece takes just under 2 hours, and I had no issues with disconnects or other.
I do however have clicking noises form the top right belt. I think it’s the belt that touches one edge of the belt guard.
Windows 10 connected directly to the Maslow AP with no other network connections.

what size frame are you using?

also, when you are cutting, are the belts tight or do they have slack in them?
a video of it cutting in the bad areas is frequently useful.

My horizontal frame is holes in my concrete garage floor. 13’ x 13’. I suspect it eliminated flex.
The part I really don’t like about vertical frames is having to use a ladder.
It would be nice if there was a bigger community of owners so we could try our Maslow’s on each others frames to compare behavior.

ME TOO. I am 100% in the same boat. It feels like we’re making slow and steady progress towards things getting better and better, but the cost in frustration is very very high.
This looks spectacular, great work!
