Dan, look how I implemented the belt clamp, can be useful

[Aliakber]

I’ve rechecked it many times, and last night it occurred to me that this behavior might be caused by a difference in the diameter of the gears.
The thing is, I use timing belts and stepper motors from an old printer. Two identical engines stood in different nodes of the printer and it turned out that they have a different number of gear teeth: one 14, the other 15. Rearranged the gear, now both 15 teeth and everything works fine!

I have a question

my robot draws curved squares. The sides of the squares are 100 mm, but one diagonal is longer by 10 mm

The motors are the same each winding is 7 Ohms
Weights are the same, 150 grams
Power Supply 5 Volts, 2 Amps
Everything works well, quickly, nothing is heated, but the square is always skewed to the right.
Any ideas?

Hey Dan!

My work is done
https://yadi.sk/d/QXhNosq1rzSyGQ
I apologize for the fact that I spread the file on file sharing, download and do everything as it should, on github
I edited your *.jar file, named it makelangelo 7.11.2
It works on arduino UNO + AMS
The “home” point is located down 600 mm from the axis of the motors.
Added the paper size I needed 1050 x 2100
If necessary, I will be able to maintain this product by adding some changes to it. But I’m not a programmer, I’m an artist, and Arduino and Java know so-and-so .
Have a nice day!

Ok, let it be a hard way. I’m open Makelangelo in Eclipse, but can’t find the “Home position” options. Where should I search and what is the name of this parameter?

[Aliakber]

it’s not my code, it’s yours, Dan.

7.11.0 – it works on arduino uno + ams

Dan, please tell me how to adjust the home position below, 1000mm down from the axis of the motors. 210mm is too high.

[Aliakber]

Hello everyone! My English is not so good, I’m from Russia.
Here are the firmware + software for UNO+AMS that work for me
Makelangelo win uno ams

[Aliakber]

Michelangelo Software is a wonderful tool. But it formats 2A0 and 4A0 which you want to do the robot with a width >1500 mm. With this width home position will become unreachable because the belt tension will be excessive, the pen does not rise to a height of 210mm.
Is there a way to lower the home position a meter down from the axis of the motors?
Is it possible to do this by editing files attached in Makelangelo-7.11.0-with-dependencies.jar -file?

[Aliakber]

Try this release. Software & Firmware look in the same place
