30mm 75° Annex Cube test, 6.5 minutes.

I have been running though some detailed calibrations of this printer and decided to change/test some different belt tensions. I am currently using GT3 9MM belts. The registration drive spec for tension is 17lbs * 1.5-2.0. This is 25.5-34lbs. I am getting VFA's from 100-150mms and I cannot seem to get rid of them. My thoughts are the 2504 motors or some bad rails from too many benchies. ha ha ha.
Anyway, feels good to blow some steam off and let it rip to see how bad it is.
Not a good print with the bridges. Should have slowed that down to get a better top and other.
This is ABS, 450mms, 40K acceleration. 50 square corner/Jerk all but external perimeters @ 450mms, 30K, 50SCV.
0.010 PA @ .02 Smooth time all areas.
Using the new MPC loop heating control for extrusion temperature. I think it's a great idea! Thank you whoever participated!
There is some VFA when it changes through the 100-150mms, but hard to see. I may try some other motors and considering going belt drive so I can move the VFA around with gear ratio change.
320x320x400 print volume, cross gantry, 1PZ Z system, Goliath hotend w/VZhextrudort extruder twirl gears. 48V drivers on 5160's for XYZE. Z is 24V running on Octopus Pro v1.1 w/723 MCU.

Your machine keeps getting better and better. Nice job!

What is this printer? Custom build? I love it. Looks like a k3 and vzbot has a child.

[@MrRocksalt]

Custom crossed gantry printer. Step 1; open drawer to find spare parts, step 2: mount them, step 3: yell "hold my beer!"

Looking good on the video! ;) Go belt drive, it did wonders! Really impressed by your cooling.. but the noise.. i cant live with it xD

[@MrRocksalt]

Waiting to see some stuff from you.. Also thinking how I want to do it. Time will tell.

[@DannerD3H]

@@MrRocksalt haha as soon as my wife is done with her exam (Tuesday) I will be able to get stuff done again xD

[@VaporizationEnt]

Nice Work! I am also running 2504s and also have VFAs and increased motor noise around 100mm/s. According to Vez3d that is Normal with the 2504s and should not be a Problem at higher Speeds.

Did you see the flsun new machine uses a cpap fan? I guess they saw your video.

[@jarrettbullion1545]

Do you have any open source ducumentation on this printer. Would love to see a close up of some of the parts in this build

[@MrRocksalt]

No, I do not. But it is a straight forward build. Z system is a little different, can see some other videos I made on it's operation/design.

[@jamesm3268]

Are you using orca slicer? If so have you got fill in gaps everywhere? There is gaps on your top surface. Sweet printer I'd love to see a run down of it mechanically!

[@MrRocksalt]

I try not to! I prefer SS and Cura. PA is a little too high for the top and I didn't do a PA change for other features like I normally do. Goofing around again, as usual.
