I have the Maslow 4.1 running 1.04 firmware (wanted to update to 1.05 but apparently needs to be done via USB cable and couldn’t find info and how to do that).
I ran a 3x3 calibration and it worked first time without a problem, decided to use manual controls to “drive” it around the board which started of ok but when I hit the Home button I noticed one of the belts (bottom left) had not been keeping the tension and jammed up on the spool.
I assume I’ll have to pull it apart to clear the jam and I suspect the belt maybe damaged.
Any advice?
On another note one of z axis step motors periodically stops working, I’ve seen several posts about this and it appears it’s be a faulty PCB. How do I get a replacement?
Quick update, I decided to take the machine apart to free the jammed belt but as one of the z axis motors is not working (or works periodically) I can’t move the router and belt spools up to free them from the thread. It’s the classic stuck between a rock and hard place. I guess I’ll have to unscrew the motors from the sled. 1 step forward 2 steps back.
One suggestion with z motors might be binding due to slight misalignment. Loosen the bolts a bit to the z motors but keep in place and then try moving all the way down and the. Re tighten z bolts and see if that helps .
To install any firmware over 1.0 you have to do it over usb the first time, so realistically you were probably on an older firmware for this calibration.
If a belt is slack while the sled is moving then you have a bad calibration, could be for a multitude of reasons. Best course of action would be to go watch the most recent video Bar put out of how to do the calibration properly, you might pick something useful up from there
Hi Dano
I ended up removing the 2 support risers and unscrewing both motors from the sled to the lift the machine off the sled. I was able to drive 1 of the z axis motors up and then swap the cable from the other z axis motor to the good port on the PCB and drive that one up.
It’s definitely a faulty PCB.
At this point I was able to unravel the jammed belt and pull it all the way out and then retracted all and hopefully the belt is ok.
I was in the middle of calibration and had this same thing happen! The right Z axis is the one thats sporadically working, is yours the same problem child? Anyway during the calibration my belt jammed pretty much 100% looks like yours, mine did get mangled and is in two pieces. Was getting ready to make a post about it and seek guidance when i saw this.
Was looking as maslow sideways bottom z axis. Also followed your tip and swapped the cables around to lift up the problematic z axis and the motor iself has zero issues so does seem to be the pcb. One step forward two back lol
