*gasp* WOW!

No, really. I’m a little disgusted with myself that QA let such a serious bug through. I will make it top priority to get it fixed.
Give me 24h to correct this, please.

Please don’t stress.

I am glad to know I am not simply losing my mind.

I will keep checking back.
Many thanks!!

I published the update earlier today. Go get it!

Thanks!! When I go to the github I can download zip or clone to desktop. Either way the Windows version does not have the java file.

The download latest version has the java file, but is still version 3.

Am I missing something? Thanks!

The latest release on the makelangelo.com page is updated; the github master branch is not what you want, unless you’re looking to rebuild the JAR file from scratch with Eclipse.

…which is great if you want to make a tweak to the program and then send it back for everyone to enjoy.

Thanks. I followed the link and downloaded the software, but it does not run properly here on PC.

When I open it up there is no toolbars and cannot connect my bot.

The MacOS version won’t run either. There is no Makelangelo.jar bundled.

Any suggestions?

Where did you click?

I go to makelangelo.com, then click “download the software for *windows*” and BAM, the jar file is there.

Please suggest a way to make this more clear. I think you’re the third person who’s said they download and the file is wonky. :T

Not a problem with findingthe link.
However, when I click the batch file in Windows, the software does not open properly. It opens, but no clickable buttons or toolbars or anything. The Java text list numerous errors.

On Mac, there is no .jar file. So nothing working there either.

An aside, I hacked together a bot using v5 on Mac. I have a 3’x4′ sheet of 3/4″ ply (everything thinner at my local shop was too warped to use), I screwed blocks of 2×4 to the back and mounted my NEMA 17 steppers to them with 90 degree brackets and vibration dampening spacers. I bought a new 12vDC 1amp power supply and wired that direct to my Motorshield V1.

If I do the “stepper test” example, the motors reliably return to the same place EVERY time.

When I upload the firmware_ams example and set home, it seems that home drifts. after drawing for a few seconds and pressing halt, when I click “go home” it goes to a different place.

I have tried using spider wire 65b test braided fishing line (it has no stretch) and timing belt on my pulleys and the result is the same.

While using pulleys, I had counterweights on the outside and a light weight at the bottom of my pen holder. While using string, I wound 15 or so extra feet around the pulleys and only weighed the pen holder (there is no “tag end” on the string to counter weight.

When I open the jog motors dialog, they don’t reliably respond. Sometimes one click goes pretty far, sometimes a low hum and no movement.

I know the steppers are fine, as when I do the stepper test example there is predictable and repeatable movement even if I change the RPM to 200 or higher. Also I changed the stepper example to 200 steps for each example and I get 360 degrees of rotation, so I am sure they are analogous to the ones you show in your kits.

My current weight setup is a water bottle with less than an ounce in it. Previous attempts have been pocket knives, wrenches, and rolls of tape.

I got a pretty cool drawing using “Blocky” but it was pretty squished. I got another good one using zigzag, but towards the end the pen went 5 inches above the paper.

Any suggestions? I have tried to research calibrating the machine, but little info available.

What are the errors, please? What version of Java are you running?

I haven’t seen drift like that since I stopped using line. Timing belt has been perfect in all our tests.
The only way for timing belt to be bad is if the current to the motors is inconsistent. On the v2.5 kit the only way that happens is if the power supply is junk. As you’ve put this kit together yourself, I can’t be more certain.

If you’re getting squish, this may help: https://www.marginallyclever.com/blog/2014/10/how-to-fix-9-common-polargraph-drawing-problems/

Any small weight should work.

Thank you for all of your help.

If I use timing belt, what is an ample weight? i.e. if I use water bottles on each side and one for the middle, how full is a starting point?

I see that string may not be the best choice. Thanks!

I put maybe 1″ of water in the bottom (2cm). More if you use spray paint.
