I have been wanting to say yes but I have to test things. I am happy to work with you to make your project a success.
I’m sorry I didn’t get notified of your replies. I’m working on updating my notes now.
For rotary stewart platform I send angle values for each actuator.
For linear stewart platform I send distance values.
I calculate both possibilities in Robot Overlord and generate the gcode there.Super cool! Pics?

Makelangelo firmware is deprecated because it does a less-good version of what Marlin firmware already does. So I recommend switching to Marlin to do the exact same thing with a smoother experience. If you have any trouble switching (or after that) ping me again. I’m keen to help.
Have you tried using Tools > Simplify or Tool > Reorder? these reduce the amount of travel moves and can greatly shorten the drawing time.
If I’m misunderstanding your question, please tell me more.
Do you mean it goes down (when homing) and then up (to 0,0) and nowhere else? That’s probably invalid EEPROM. You’ll need to “Configuration > Restore Defaults” and then “Configuration > Store settings”.
You might also see a message when the machine turns on saying “reset EEPROM?” and you should agree. Usually this happens after a firmware upgrade.
Choose “Reset.”
Is it a new servo? the servo wires have to be … twisted? see here: https://mcr.dozuki.com/Guide/3.+Pen+Holder+Assembly+2023/40?lang=en#s447
An exciting idea with a number of challenges.
The maximum diagonal length of a 12×8 wall is 14.4, much less than our longest belt, 20m. no problem.
The maximum recommended length for the stepper motor cables is 5m. if the electronics are mounted in the center then this should be no problem. However the electronics mounted top center would be rather difficult to reach! This might be solved with a raspberry pi and a USB wifi adapter.
When the machine “goes home” at the start of a print the outside weights go all the way up and the pen holder goes all the way down. it would hit the floor and belt would pool there. Conversely, when the pen head is near the top center the weights would hit the floor. both of these are an issue. The tensioners (https://www.marginallyclever.com/products/bearing-tensioner-diy-kit/) might help a little, but I can’t confirm it would be enough – I simply don’t have that much wall to reproduce the conditions.
The existing pen holder would struggle to lift the pen off the wall at the bottom of an 8m wall. As the belt gets longer, the effective push of the lifting tool takes more time. There has been some exciting work from DIY makers int he Discord channel to use alternative lifting systems, as well as experiments in adapting for spray cans…
..which raises the question of appropriate mediums. The Makelangelo is normally run with pens, markers, and especially Sharpie markers. They tend to last about 2h before beginning to fade. Spray paint cans would need to be replaced at regular intervals. Chalk/conte/charcoal et al are consumed even faster.
SO the answer is … maybe? I’m willing to work with you to find a solution. I’m interested in developing the spray head system and doing outdoor pointilism mural work, perhaps we can find a mutually appealing solution.
Hi Ronald,
all the parts are open source and here’s just one of many places you can get them: https://www.printables.com/model/407394-makelangelo-pen-holder-2023
Settings > Paper Settings > Shift left / Shift up will adjust the paper position, but the drawing will always be centered to the paper.
What is your application? Maybe we can add a feature to get what you want.
@nadeego please post your entire conversation with the robot. if all you see is “you:400” several times then your robot is not talking to the app. that means you have either a robot problem or a USB problem.
what version downloaded from where?
You’ll need your own computer. 🙂
We ship North American power supplies so you might need an adapter. Any 12v2a DC power supply with a 5.5 barrel jack connector should also work.
Thank you for the links. Oh snap… that will take quite a bit to clean up.
I hope it’s a typo? What URL are you getting the firmware from? I’ll try to fix the old post and point it to the github, plus find that missing letter.
Yes and yes!
Answer was found to be 16 tooth pulleys instead of expected 20.
Hey, thanks for reporting this. I’ve added an explanation to our step-by-step guide here:
https://mcr.dozuki.com/Guide/1.+How+to+use+Makelangelo+Software+7.24+/5?lang=en#s428
Does that help?
Did you home the robot before attempting moves?
G28 XYwill home the machine. after long periods of inactivity it may turn off the motors for power saving and force you to re-home the machine.
You did everything correctly.
In ~7.29 I started to clean up a lot of code that was worked but was really poorly constructed. We have temporarily lost the ability to change the visual of the machine. I am actively working on adding that feature back in (see link below). I would love your help with making it happen.

I see nothing attached.
The connect button will never be unavailable but it might have zero USB ports to connect with.
I do not have permission to see the pictures. Try imgur.com?
@Vincent98 yes, here’s the marlin fork I use:
https://github.com/MarginallyClever/Marlin-polargraph/tree/polargraphIf you get another problem please post your full error message and maybe a pastebin of your config settings. Then we can see what you changed and maybe suggest specific fixes.
