Identical artifacts/issues on two parts on the same print job
-
so you are on rrf2 here.
-
@Veti mototrs are part no 17hs19-2004s1.
I dont think theyre the culprit because i have had good prints before with them. The printer sat for 6 months or so so i came back to a bunch or random issues and not remembering much about the printer -

those are 2A motors. you are running them with not enough current. set the current to 1500ma
-
@Veti done. would that cause my issues or could there be more? its ran fin on 1000mA current since i got it, but now that i think of it, the prints were never perfect.
-
it could.
-
@Veti also would you know where i can find a chart or something for setting thermistors? i need to adjust both of my printers. this is the bed heater NTC 100K thermistor ( Beta 25/50 3950K-1%
-
@Turbo said in Identical artifacts/issues on two parts on the same print job:
3950K
thats the beta value
-
@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.

@Turbo For fun heres my other printers config file running rrf3 if you want to rifle through it

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

@Turbo said in Identical artifacts/issues on two parts on the same print job:
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?
-
@Turbo said in Identical artifacts/issues on two parts on the same print job:
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
