Finally parts for new printer are arriwing…:slight_smile:
Cant wait to finish it,it will be a beast :slight_smile:

Haribo… I almost choked on a grape when I saw that!

Iplease dont choke,it isnt worth it :smiley:

Hi that part doesn’t belong there. That goes on the motor for the belt not a threaded rod.

@Scottie_D369 depends on the design - belt driven leadscrews would take the flex of the flex couplers out of the error equation (especially on really big, heavy beds).

Clay printer or CNC mill or plastic printer or laser cutter. No doubt the options are wide open. I do not know how good the speed will be if it is just printing plastic though…unless it uses DC motors with encoders.

@NathanielStenzel why would it be low speed - these look like pretty common printer parts, only larger and longer.

@Alan_Thomason I was under te impression that the threaded rods were for all axis. If so, it would be slower than direct belt drive unless there was a ratio on the belts and then the ratio might make up the speed difference.

@NathanielStenzel my printer uses two leadscrews for the Z-axis…

@Alan_Thomason ah. Alright. Sorry. I was not following along with your project.

@NathanielStenzel I don’t have project, so no offense. I just realized that it’s all about perspective - my Rigidbot printer has two leadscrews for the Z-axis. I forget that many printers only use one - sorry for sounding grumpy, it wasn’t my intent.

@Alan_Thomason no problems here. I take it your two z axis threaded rods run off of the same belt? Is there a bearing in the bronze part that goes on your rods or are you just going to keep them lubricated somehow?

My printer (not my design by a long shot) is driven by two steppers in the Z - one motor/rod combination on each side of the bed. I’ve heard several conversations regarding the Z-axis error introduced by standard spiral shaft couplers between the motor and the leadscrew. The idea of driving the screws with a belt would eliminate the height variation caused by the weight of the build plate and print. My printer doesn’t have couplers or belt drive; the leadscrew is integral to the motor. Therefore, no height variation; but, it causes other potential problems such as binding and Z-axis wobble. Everything seems to be a compromise…

All axis will have mgn12,also z axis.
Becouse it will be big,z axis will be powered with two tr8 connected with timing belt and one motor.

Where did you purchase the mgn12 from? How is the quality?

banggood. quality is good, all carts drive smooth with no play(i have five of them).
cant tell thet these are chinese clones.
should be ok for corexy.

Awesome! If you can provide a link for them it would be appreciated! I planned on using them for my corexy build.

banggood search mgn12
