Marlin SCARA arm

[napalm1432 0]

Hello all,

I'm currently building a SCARA Arm 3d printer and got some parts working.

I'm using the Marlin firmware by qharley, edited byJCERNY to drive the arm.

So far i got it to home to endstops and make it move. i'm having problems calibrating home positions though and i'm hoping you guys could help.

It's a single Scara arm so it may be different than the usual morgan scara arm, and maybe that's what's giving me problems?

the goal is a single arm, with a theta length of 162 mm, and the same for the psi length also 162 mm.

I got the steps/revolution set right.

Some other problems i'm having is that sometimes when i want the arm to move say 10mm, it just keeps rotating, this doesn't always happen though.

My question here is can you guys help me get this to work since there's not alot of documentation about getting a scara arm to work with marlin.

I made a github for this so if you can please commit changes.

If anything is unclear or more information is neccesary please let me know.
