Hey team thanks for the add. I’m new the the world of Maslow CNC routers. I bought my second hand here in new Zealand and I’ve had it set up and running for over a week now but I’ve been having issues with the work piece being cut off square. It doesn’t seem to be consistent either. I’ve calibrated it 3 times but still no luck. I’ve read a bunch of forums from here and still I’m stumped. I’m using the CNC to make big farm signs out of slabs that I mill on my sawmill so I need it to cut square. Any help would be much appreciated thanks in advance

Can you post some pictures of the M4 on your frame and of the cuts you’re getting?

Ok, this is the original maslow, not the maslow 4. what do you mean by ‘not
cutting square to work piece’?
are you talking about the sled not staying against the workpiece and so the Z
axis not being square to the workpiece?
or are you talking about cutting what should be a horizontal line and that not
being square to the workpiece?

As in when I load up the g code to ground control it all square on the screen but as soon as I presss start it cuts the image on the piss I’ve calibrated again but it’s still out. Instead of fucking another sheet of mdf I cable tied a vivid to the router to show what’s happening. It also has a slight wave in the work piece also.
that indicates that the chain has slipped, you need to reset the sprockets and feed the chains out again.
I’m pretty sure it hasn’t as this is the 8th time I’ve calibrated and I’m pretty careful. Someone said I should balance my chains. Not 100% sure what they meant.
If the chains are not where the machine thinks they are, this is the result. It
can happen from powering down the machine when it’s not idle, or from a chain
slipping.
you don’t need to re-calibrate, but you do need to feed out the chains again.
you need to move the motors so that there is a tooth straight up (the 12 o’clock
position) and then either put the marked link on that tooth (if you marked the
chains after they fed out during the setup process), or feed them out again.

No I haven’t marked the chains. So I put the motors at 12 o’clock then run them out them mark the chain link that is lined up with the mark on the sprocket? And then if they skip a tooth I can just put the motors back to 12 and put the marked chain link back on the marked motor tooth ?

almost, there is a button in the settings screen that lets you set the chains to
a known length. after you put the marked link on the 12 o’clock tooth you hit
that to tell the machine that you have done so.

Ok hey mate thanks all your info has finally fixed my problem. I thank you. I have one more question. My USB connection sometimes gets bumped and it loses connection. I try resuming it but nothing happened. Then I thought I would just send it home and start again. But now it thinks where it finished is home. How can I fix this and how can I resume when this happens again. Thanks in advance
the best thing to do is to use hot glue to make sure the USB doesn’t come out
it’s probably worse than you think, when you have an unexpected disconnect, it’s
probably losing it’s position so it doesn’t know what length the chains are any
longer.
