Identical artifacts/issues on two parts on the same print job
-
@Veti gotcha. Thank you for answering my questions. Im going to try a test print or 2 with the updated settings and report back.
-
do post your final config for another check
-
@Veti Its been through some revisions so theres some leftover code that i keep incase i revert back.

Z1000
is your z motor a different motor?
-
@Veti its a 5:1 geared stepper motor. 17hs15-1684s-pg5

17hs15-1684s-pg5
set that to 1200
you should got for around 75% of the stated current.
how heavy is your bed, that you need 5:1 stepper drivers?
-

Z423
I dont understand this value. that just feels wrong.
what kind of leadscrew do you have?
-
@Veti it's not too heavy. Approx 300x 200y, with some 2040 extrusions. Main reason is the z axis is belted rather than leadscrews
-
assuming you have a gt2 setup with 20 teeth
motor is 5.18:1
that would be 414.4 -
@Veti im not sure the exact gearing, but it does drive-->middle pulley, out to two more pulleys on either side. let mee if i can count the teeth
-
it says so on the spec page you linked
Gear Ratio: 5.18: 1
-
@Veti not of the motor, im not sure it uses all 20t pulleys, there might be a combo of different counts
-
@Turbo
only the one on the motor counts. -
@Veti oh okay. let me try that value and see what comes of it
-
@Veti printed a 20mm cube at .35layer height. Slicer says it will be a final product of 20.15. actual is 20mm on the dot.
-
I think the problem is cold extrusion. Your thermistor settings were really off and you're printing fast and with a thicker layer height really pushing the flow rate. I think that's why the top layer looks more like strings than proper fused extrusion.
Now that you have the proper thermistor settings in place I suggest you go through this guide and recalibrate your extruder and find your maximum flow rate, and from that you take your chosen layer height and width and determine your appropriate print speed.

@Phaedrux Just finished pid tuning and printing a square to verify settings. Will work on e steps next, although how much could it change due to a bad pid value?
-
Well it's more than just esteps, it's finding the max volumetric flow of your hotend and extruder and then adjusting your print settings to stay within that limitation.
-
@Phaedrux
so far e steps look likem92 e407.42
max vol flow rate calculated to be 12.04107575mm^3 / s^2
Max sugg speed for .3 layer height and .6 line width with a .5mm nozzle is approx 66mm/s at 210c.
still going but thought id post an update
printing the box testing for flow. is it okay to use .3mm layer height du to the larger nozzle and thats what i normally print with
