UM3, moving filament by a fixed value

[rebekah_harper 51]

Hiya,

 

I was wondering how I could instruct the UM3 to move filament by 100mm and check to see if it does actually move by 100mm.  thus confirming the steps per mm. 

 

cheers

You need to enable dev mode and access the machine using ssh root@yourprinterIP and the password is ultimaker

 

then using sendgcode you can send the gcode you want like “sendgcode G1 E10 F300” (where E is 10mm and F300 is the speed

 

Ofc the hard part is to change the esteps of the um3 since editing the json file can very easily Brick the printer if one comma or dot is misplaced

thank you for that.  

I know, the bricking issue is at the for front of my mind but there is something bugging me about the upgrade I did and want to check it before I start getting emotional about it. 

 

will let you know how it goes.

I am going to need a little more help. 

 

I thought that I could do it through putty but it's not recognising the commands

 

I did try through browser but that didn't seem to get me any where 

 

cheers

Try to send other gcodes like G28 Z0 to home Z

 

if the E moves doesn’t do anything is probably because it has a minimum temperature protection. If um3 marlin allows it you should be able to send a M302 to allow Extruder movement when the tools are below 170C

It's saying command not found.

 

I am typing sendgcode.G28 Z0

 

I've also tried sendgcode G28 Z0

[rebekah_harper 51]

this is what I am working with

Why the dot? 

 

sendgcode G28 Z0

[neotko 1,368]

Oh wait I see. Maybe the changed something on new firmwares (I don’t have a um3 anymore since well, long history)

 

you should be able to move to Griffin and there should be a sendgcode.py the. You can do python sendgcode (or something like that? To run the python, then ince inside sendgcode program you just send gcode directly to the marlin like a pronterface

I am getting command not found for sendgcode
