Hi, finally got time to get my maslow built (batch 2 order). When trying to get setup to run calibration however, I’m see an error not detecting bottom left encoder.
The encoder board itself seems to be OK. The green power led on the ethernet connect is lit, and the amber led flashes when moving the belt.
I also swapped ethernet cables around, connecting the bottom left encoder input on the controller board to another encoder board that was working. I still see the bottom left encoder error after doing this.
Also tried power cycling a few times. Does this seem like a bad controller board (don’t see any visual damage to the board)? Any help would be appreciated.
I think that you did a great job testing. This does sound like a controller board issue to me. I’m not sure why just one encoder port would fail since they are all on the same SPI controller, but maybe a bad solder joint or something like that could do it.
Shoot an email to Anna@MaslowCNC.com and we’ll get you a replacement in the mail ASAP.
Hi bar, thanks for replying. I sent Anna an email regarding a new board. It is odd if they are all on the same spi bus. I didn’t see any visual damage, but maybe I’ll hook up some analyzers and see if I can catch anything further.
Hello I run into a similar issue. I finally assembled my Maslow and during calibration I found out that only 3 encoders work ( green light on, yellow one works when the belt is moving). Only my right top encoder does not work and the lights are off. Running a test it says:
[MSG:WARN: Encoder read failure on Top Right]
[MSG:WARN: Encoder not found on Top Right]
The green lights on the pcb board are on for all 4 encoder. I swapped the cables to rule that out as a source of error but no luck. Could the encoder be faulty or may the problem lay elsewhere. The red light on the pcb controller board is also flashing.
Just wanted to post a follow up to my original issue in this thread. I received the new controller board today and installed it on my unit. All the encoders are now detected and I am able to retract all 4 belts. Moving onto calibration next.
Similar story for me. Bad encoder, green lights on the maslow ethernet ports, but no lights on the encoder board. Tried swapping cables/ports.
I disassembled the problematic arm and soldered on some leads to the 3.3 and GND. The green light on the encoder comes on when I use my bench power supply, and I don’t detect any shorts in continuity mode.
All resistors and capacitors are showing appropriate values on my multi-meter.
With the leads attached to my multi-meter I plugged the problematic board back into the maslow, and I don’t see any voltage across the 3.3v/GND labeled pins.
I’m guessing this means a bad ethernet port on the encoder board?
I emailed Anna asking for a new one, just trying to help debug for others!
I received the new encoder which works perfectly. Thanks fort that. While dismantling the Maslow I ran into an issue where the screws of the arm as well as the one on the clamp were too stripped to un tighten them. I tried to drill into the head of the screw which only made things worse. I accidentally chipped a peace of the clamp and the arm. Would it be possible to reprint those parts ? And if so could someone kindly point out what parameter I should tell the printshop so it doesn’t turn out too brittle or ductile. I would normally buy new parts but shipping to Canada costs more than the replacement parts costs and I am on a tight budget right now.
