I have same question.

How do you want to mount the RobotDigg Bulldog Extruder?

I found the issue, the red wire of the connector on the Nema was half broken, wich gave the issues.

It's fixed now ;)

Cheers

That's friendly but i have a mendelmax 1.5, i was refering to this http://www.robotdigg.com/product/698/Mounting+Plate+for+Bulldog+Extruder.

I ordered the right version but the extruder just james when trying to load from that side, the other side loads fine.

Any idea what side you use?

My robot digg bulldog arrived today, i chose the mounting plate to the right, but it can't extrude from that direction, the motor just jamms when tryin to load filament, from the opposite side it loads just fine but i need a left mount for that, pff, they also forgot the 3mm connector. When you order something these days it's a miracle when everything ordered is delivered.

Thanks alot, i ordered a robotdigg bulldog xl myself, and i will probably Order the same Drive gear as you are using.

Mini just logoAndrew Wade commented ago

Yes but i use a different extruder gear as the robot digg drive wheel is not toleranced correctly to the shaft of the stepper motor so its slightly eccentric and can slip. I will find out the drive wheel/gear i use and get back to you with its make and steps are use.
