New Delta Design

[KAS]

Just started my first print with a RADDS+DUE board running Repetier .91 and DRV8825 drivers. I wish I would have never messed with the smoothieboard. I never got that thing printing very well, it was a pain to configure and use that config file, and the modified config, all the m-codes to do everything. I'm back to running Repetier server on my Banana Pro, I'll see how it goes! Hot end and heated bed all calibrated. no more bouncing bed due to the poorly tuned PID, its dialed in such that it takes ~30 seconds to settle after a 3-4 minute warm up to 90C.

So far layers are stacking up nicely and laying down nicely. I was getting symptoms of loose belts and all kinds of other things bugging me. Now its all running quite nice. DRV8825's on 32 microsteps make very little noise! I have some RAPS128 drivers coming, 128 microsteps are supposed to make it dead quiet - now to quiet down my power supply fan and I'll be happy!

What were your PID settings afterwards? I can't seem to figure mine out. It's worse with the aluminium heat spreader on and never settles back down.

I even cut a new snowflake hoping that would help with more mounting holes (plus mine was warped). No go on that.

room temp to 100c = .005" lift at the center.

I think P=20 I=.1 or .05, D=.1 or .05 is usually what takes to get it to settle in nicely and quickly. Smoothieboard was set to that too but it didn't settle in the same way repetier does. It could be clock speed, or something else that causes it. I also noticed that repetier sets power at 100% until its within a certain range whereas Smoothie will use P to set the power ramp - same settings heated up MUCH faster on Repetier than Smoothie.
Its difficult to dial in the PID on a smoothieboard because all you have is the temperature to go by, there is a feedback value that you can watch but its difficult. I watch the power graph to dial in the PID values rather than the temperature graph.

JFettig, could you tell us what the complete Z height is for this new printer?
It looks to be similar to a Rostock.

It's roughly 370mm depending on the build plate and hot end mounting

I'll have some polycarbonate sheets coming in soon! I'm planning on making an aluminum build plate as well.

Thanks and it will be nice to see the finished printer!

I can't say I ever 'finished' this printer, but its much closer

It's been printing away, lots of PETG(Inland branded esun from microcenter)
