Delta M301 firmware ( Marlin )

[divemasterbill]

Where do I find Marlin firmware for Delta M301?

Hi,
You can find it here:

This is the link I think is for my machine http://www.geeetech.com/forum/download/file.php?id=2495

It downloads but I can't open it
My Geeetech Me Creator opens to Arduino IDE and I can see Marlin and work with it. This does not open to anything.?

The way to upload 301's firmware is different from Mecreator,here is the steps you need:

And the firmware for 301 is not open source,that is to say,you can only upload it and can modify it.

Hello, Where can I find explanations on what the " Delta " settings on my 301 do and how to set them . I am having a bad time trying to calibrate . The 1st layer is either too thin or too high to stick , it is very uneven from center to edges. It is also inconsistent , I get 1 decent print then the next day it is all out of order again. Please advise.

Where do I find definition / purpose of all the "Delta" settings ex; diagonal rods , smooth offset , effector offset, carriage offset, Delta radius,

Here is the relevant settings in G2s's firmware,you can refer to it:

Thanks William for your responses , I can not get this M301 to print with the 3 color hotend! I have tried 2 degree increments from 200 C to 260 C I bought a complete 2nd extruder right from Geeetech I have tried stepper currents from .5v to 1.1v measured on the poteniometer to ground . I bought Geetech aluminum extruder sets (3) . I have tried min to max tension settings . I can not get filament extrude with enough volume . ie. it just barely comes out of nozzle . I changed complete extruder assembly , same problem . I have tried 6 different rolls of filament . I made an adapter mount and put an E3D extruder on and it prints fine . I go back to 3 color extruder and I can not push filament thru fast enough . It either jumps the tension arm or stalls the steppers depending upon tension and current settings. If I take out bowden tubes I can push filament thru with the plunger tool supplied with M 301 without too much force . I don't know what else to try . Please advise I use ABS filaments only . Thank you Bill D.

Make sure the bowden tube have been plugged into the tube deepely enough.
There's a possibility that the temperature is too high and the filament melt in the PTFE tube or the tube is expanded and then prevent the filament coming out
to the nozzle.

You can also disassemble the hotend and see if there's anything wrong or if it's clogged somewhere.
