I have a vertical setup with a 10’ x 8’ wood frame. Calibration went well and I was able to do simple testing manually moving the Maslow, all good there. After unplugging the Maslow for the day, when I went back to do some cuts the next day the Maslow wouldn’t move. On the screen it would show it moving, and the motors were making noises, but nothing moved. (although z axis did move). I unhooked the Maslow from the frame, retracted/extended, put it back on the frame and it started working.
So, my main question, is this the expected behavior? Shouldn’t I be able to turn the power off and then resume without needing to take the machine down and resetting the cables?
This is one of the most requested features and we’re planning to add automatic recovery from power loss. At the moment any time that you lose power you will have to retract the belts and extend them again to re-home them.
Hi all,
So I’m having similar issues ,
I’ve calibrated , then released the tension, retracted the belts , inserted the cutting bit , placed the ply to be cut on the frame , extended all belts and placed the Maslow onto the frame etc and applied tension….
I’ve set home for z
Loaded the Gcode… and can see the pink dot on the PC telling me where the CNC is on the frame….
If I then try to make the Maslow move to where I want it to be on the ply.. the cooling fan starts but the Maslow doesn’t physically move and if I look at the PC the pink dot is moving ….
There was no power loss
I’ve gone through the cycle of retracting all belts and extend them etc but when it comes to manually control the Maslow to position it on the plywood it just doesn’t move
To prevent the belts from potentially breaking the machine will lock out movement until after “Apply Tension” is pressed and it confirms that the frame it is connected to matches the size of the frame that it has stored.
When you press “Apply Tension” what information do you see the machine print out?
Sorry for the delay, I’d opted to re calibrate,
One thing I’ve noticed though is when the Maslow is being pulled upwards, the lower part of the sled is lifted off the surface off the spoil board , I’m guessing when that happens it’ll throw off the calibration calculations?

it could a little bit. make the sled slipprier or tilt the frame back more.
Ok completed calibration,
Retracted belts inserted bit defined z home,
Placed plywood to be cut on spoil board , then extended belts and applied tension,

also, when i’m extending the belts there seems to be moments when the belt i’m pulling on seems to loosen or extend quicker than the speed of the motor/gear… is this something wrong?
Hi guys,
Ok some feedback, and I wish I had some good news , I’ve been attempting to calibrate for over 10 days and there just seems to be too much that can go wrong or throw off a calibration , even when I manage a successful calibration and attempt to do a first cut , it’s consistently then reported that there’s an error of deviation .
I’ve sanded the spoil board , made numerous adjustments to the settings retracted and extended the belts so many time that I’ve lost count .
I don’t want to give up, so humbly requesting to hear on any updates etc that can possibly help me get out of this seemingly endless cycle ?
So I went back to Horizontal , though on the wooden frame and not on concrete floor , I put the values back to how you have it in the video but had to raise retraction force to 1600 as at least one belt would not fully retract unless I raise the force.
Calibration seemed successfull….
I released belt tension inserted router bit and homed z , retracted belts , seemed to be some belts not fully retracted so upped retraction force to 1700 , seems hit and miss but eventually belts retracted, I placed a board to be cut, extended belts , applied tension but only 3 belts tensioned , top left didn’t at all .. seems familiar occurrence….. so released bolts , and went through retraction again, all belts retracted… so extended again and applied tension, all belts tension this time …. So I moved the router to where I wanted it to begin a cut , all seemed good… turned on router and hit Play, the CNC immediately raised Z up and then tried to move diagonally toward top right of board… stopped and I got an error 15.108 position error.. retracted all belts .. this time top right belt didn’t move … no matter what, it would not retract , so this is where it starts to be a repeat of the cycle, I keep trying to see if belt guard is doing something or I up the retraction force until it retracts .. etc , eventually the forces start seem unreasonable and I reset and try again…
Hi,
it seems to vary , sometimes one or two dont retract sometimes only one retracts and it seems to be different each time,
i’ve upped the force to try and sort that but worried it can seem very high 2200 , so often ive taken it back down again if things arent improving and hope that the activites so far will have loosened things off a little .
its a 4.1 kit
thanks and regards,

hi Bar,
to be honest I’m wondering if the firm ware is corrupt ? when i hit play i kinda expect the cut to start from where ive tried to set home pos on the board… or it supposed to raise the z drive up and then head over to the opposite corner to start cutting out the cut shape ?
can say really if its moving to fast currently, will the serial text help with that ?

That is going to depend entirely on your gcode and what your CAM settings are.
if you post your gcode, people can look at it and see what it’s doing.
