One simple trick to double your Maslow M4 speed - prepare to be shocked

[boxomatic]

If one Maslow M4 is good, two must be better, right?

Maslow #2 arrived and assembled over the weekend.

Frames extended from 10’ to 12’, and a little wider too.

Maslow #2 successfully calibrated on the larger frame with .58… fitness.

Unfortunately Maslow #1 has failed to calibrate on the larger frame 3-4 times now. Not sure if it is getting tired from all the work and whatever happened to it over the weekend or what.

It’s coming up with fitness .47 after the last waypoint. Tomorrow I’m going to try 0.75 with a threshold of .45 instead of 0.5 and see how it goes.

=> @bar The software version reported in the console for 0.75 is 0.74 still?
=> Maybe some wi-fi issues running two near each other. I was getting missed heartbeat warnings during calibration every so often:

=> I changed to wi-fi channel 6, will see if that helps tomorrow.

=> I’m getting “Error 3” showing up every so often in the log:

A command to save these values has been successfully sent for you. Please check for any error messages.
$Config/Filename=maslow.yaml
$AP/Country=CA
[MSG:INFO: Zeroing z-axis position]
error:3
[MSG:INFO: Measured waypoint 49]

(I did change the country code to CA before finding the channel number to change as well)

=> What is error 3? Is there a list somewhere? I can look for it in the code if not! I need to make sure my versions are matched up, firmware and yaml, etc.

=> Biggest issue (besides calibration) with trying to run 2 has been having multiple operators connect to the wrong wifi (maslow and maslow_2) and stop the other machine in progress of cutting or calibrating.

=> Maslow#1 drove off the board during calibration after getting spurious connection from 2nd computer (we think).

=> My laptop auto-connected to Maslow#2 while rebooting Maslow#1 and before I realized what was happening, clicked the ‘stop running job’ button that appeared (assuming it was still Maslow#1)…

I’ve since set both networks to not auto-connect, and when they are both running will have dedicated tablet/pc for each one. But you can see the argument for hard-wired connection too, especially if RF/EMI/Wifi situation is noisy.

Cord and hose management a work in progress, should be dialed in over the weekend.

Also, after cutting for a while, having job get stopped (dueling wifi), re-setting Z axis and tightening some loose screws/nuts and then found this on the work surface:

it finished the cut just fine, but I’m guessing having one of the gears resting on the plastic won’t be good long-term…

3: Invalid $ statement

that sounds like what we are seeing

Thanks David! Appreciate the errors list.

Nice setup!

After some calibration challenges on Maslow#1, and a z-axis stepper motor replacement on Maslow#2, managed to get them both operating at the same time.

We will see how it goes with the remaining ~100 sheets.

I hope you have earplugs that noise is unbearable.

[boxomatic]

ha ha, yes. over the ear hearing protectors!

This is so cool! Pretty soon you are going to have more Maslow’s running than we do

Cool setup…just curious, what are you making? “remaining ~100 sheets” looks like you are putting the M4 thru production level paces?

A Seattle company, https://hourglassescapes.com, is building ‘sets’ for an upcoming escape room experience they are building out. The panels are being routed out to simulate Inca style stonework. Two vertical panels and a horizontal panel make up a 8’ x 12’ high wall section. “You find yourself in a large room, the impenetrable and meticulously crafted stone walls fade into darkness above you…” I just made that up, but something like that! I think it’s not opening until fall but I’ll try to post some pictures of how the panels look in their final form.

I sense a Maslow community meetup coming this fall.

Closely watching your progress here. I’m planning on using the M4 as a poor business’s first CNC. If it’s good enough, I might considering running multiple ones rather than buying a traditional machine.
