Re: how to configure TMC2209 - 6 months ago

When you are in UART mode, controlling the current through firmware, it's my understanding that those potentiometer are not being used at all, their not useless because if you were to switch to standalone, "TMC2209_STANDALONE" in the firmware, then you would have to use the potentiometers to change the VREF and measure with a multimeter. I have noticed that I have one printer using TMC2209 in UAR

Re: MKS Robin Nano V1.2 Input Shaping LCD reboot loop? - 6 months ago

Tested with 2.1.2, seems to be working, thanks for the help, wonder what is up with 2.1.2.1 and 2.1.2.2 that is not working with the Robin Nano board v1.2?

Re: MKS Robin Nano V1.2 Input Shaping LCD reboot loop? - 6 months ago

I cannot completely confirm issue has gone away, however, switching to the original 2.1.2 version of Marlin will at least boot up and I don't get stuck in the boot loop.

Re: MKS Robin Nano V1.2 Input Shaping LCD reboot loop? - 6 months ago

Thanks, Seems to happen on 2.1.2.1 too, I suppose I can try to go farther back with input shaping, but with 2.1.2.1 and 2.1.2.2 I have the same issue.

MKS Robin Nano V1.2 Input Shaping LCD reboot loop? - 6 months ago

Hi, I have a Ender 3 V1, dropped in a MKS Robin Nano V1.2, and using firmware 2.1.2.1, (I also tried this with the 2.1.2.2 version, still had the same problem). I just learned about input shaping and wanted to give it a try, however, when I try to enable input shaping in the configuration_adv.h file, the printer just gets stuck in an endless boot cycle. Been trying to search all night for a sol

Re: Cannot resume print after pause - 7 months ago

So been messing with this for a bit. Seems there is a lot of buggy stuff with the MKS Robin Nano V3.x boards and the TS35 LCD screen. The first thing I found out from the wiki is that the TS35 LCD screen comes with its own pre-built filament detection and pause functions. I re-compiled the latest marlin firmware, 2.1.2.1 because it had the v3.1 env for platform.io. I disabled the ADVANCED_PAUSE_

Cannot resume print after pause - 7 months ago

Hey there, I have the following printer setup: ToAuto A 1.1 Pyramid (CR10 Clone basically) 300mmx300mx400mm build size MKS Robin Nano V3.1 with TS35 Touchscreen LCD X/Y/Z and Extruder steppers with TMC2209 stepper drivers Marlin Firmware 2.1.2.1 (Should be the latest) Attached is my configuration.h and configuration_adv.h files. The problem is that if I pause the print, I cannot get the print

Re: Ramps fried after try DRV8825 - 7 years ago

Well, Just as an update, I ended up rewiring my 3D printer for 24V, for my DC fans and other 12V items I got a DC to DC step down converter from 24 to 12 V, for my heater catridge which was 12V I just made sure all my max pid values were like 70 or so, is where it seemed to be the most common sense, at full 24V holy cow it jumped fast to 300 C!!

Re: Uneven layers issue? - 7 years ago

Did another check on my mechanics, the only thing that I could find was my eye bolts have some minor play, kinda annoying really because I just bought them a month or so ago, must have been a cheap brand. They don't play enough to cause the amount of slop that I am seeing in the model though, so I did an entire re-calibrate, found that my printer was way off, something must have happened to eepro

Re: Uneven layers issue? - 7 years ago

Did another print 20 mm/s with a different ramps board, still get the same results, less mind you, but still visible consisten uneven layer issue, never had this before, really strange.

Re: Uneven layers issue? - 7 years ago

Checked the build again, seems legit, stepper gears don't move or jiggle, they are solid, belts seem solid, effector is tight, I'm at a loss, I had this thing printing 0.1mm layer heights no problem just a week ago, great prints, no bumps or uneven layers, was perfect, now I can't even get a cube to print right, what a shame

Z probe issue - 7 years ago

Ramps 1,4, 24V PSU, modified the D1 diode and changed polyfuse to work with 24V, Z probe is a NPN inductive sensor, wired the brown to 24V, the blue to ground, and added a diode to the black and attached tothe S on the endstop pins. Was working fine, then randomly it started always triggering high. The problem I am facing is that I have switched ramps boards, switche npn sensors, and still no

Re: Uneven layers issue? - 7 years ago

I do that every print, that made no difference unfortunately.

Re: Uneven layers issue? - 7 years ago

Well, third test, went back to A4988 1/16 steps, still have the same issue. Like the whole printer just went to crap too because the Z-probe stopped triggering, and I can't get it to trigger now. Completely lost on the bad print problem. Check the mechanical stuff again I guess.

Re: Uneven layers issue? - 7 years ago

First test, changing DRV8825 to 1/16 steps, no change, same issue, next to try the Old drivers A4988.

Re: Uneven layers issue? - 7 years ago

Thanks for letting me know, updated the picture source, google drive doesn't like sharing it seems... My problem doesn't seem to be related to the link you gave me, It is smooth, my problem is if you can see in the picture, that I get an consistent uneven layer pattern at around the same amount of layers each time, I have checked and double checked, I may still be missing it, but mechanically it

Uneven layers issue? - 7 years ago

Picture of issue: I used to get very good even layers with this delta printer, almost perfect layers, I switched to drv8825 stepper drivers, 24V PSU, and recalibrated the whole thing, and now I get this fairyl consistent uneven layers that stick out on my prints. Never have had this before. I suspected mechanical, checked eveything seems fine, I suspected extrusion, I checked the extrusion, s

Re: Ramps fried after try DRV8825 - 7 years ago

You are right, I mean the motors, see at lower currents the motors aren't as noisy, but then I didn't have enough juice to get the stepper motors to work with my delta printer, so I am wondering if I switch from 12V to 24V if that will help with that or not.

Re: Marlin Frimware Issue - 7 years ago

I have since gone back to repetier, Idid notice in their configuration that its a very low number for line segments for ramps, I don't have an lcd controller, but even going lower on the line segments I still got stutter so I had no idea what was going on. Repetier seems to work fine, and I figured out how to get autoleveling working with repetier, I have magnets that screw up my conductive senso

Re: Ramps fried after try DRV8825 - 7 years ago

Yes, I have looked up the mods to use ramps 1.4 with 24V, the only thing I am worried about is will it make a difference with the DRV8825s? I will probably still stick with the standard stepper motors just because with higher voltage maybe I can reduce their noise a bit.
by Nate523 - RAMPS Electronics

Re: Ramps fried after try DRV8825 - 7 years ago

Yes these things are a bit noisy for my taste, I am using only 12V though, I wonder if anyone has experience with these guys at 24V if they are less noisy, because I can't get rid of that high pitched whine.

Re: Ramps fried after try DRV8825 - 7 years ago

well, jeez, I guess I fried one of hte drivers, because all the rest work when I finally decided to try them out. Whole mighty though they whine like a banshee!

Re: Ramps fried after try DRV8825 - 7 years ago

Allright, the ramps board is not fried, turns out it was a diode that was messing up things, got a beefier one and everything seems to be in order except I can't get these DRV8825 drivers to work, I get whining noises but no movement on the stepper motors.

Re: Ramps fried after try DRV8825 - 7 years ago

I can confirm that something is wrong with the voltage because the led that comes on when the extruder heater is on, comes on, but like very dim, is that the same power that drives the stepper motors?

Ramps fried after try DRV8825 - 7 years ago

Hi guys! I tried DRV8825 stepper drivers today on my ramps 1.4, it wouldnt turn the motor, then I went back to my A4988 drivers to test, and now they wont turn the motors. they move a little but act like they are not getting enough voltage. I also noticed that my extruder will not heat up now, but the heated bed will, I was wondering if the DRV8825 might've fried my ramps mosfet or something? Do

Re: Extruder feedrates maxed out somewhere? - 7 years ago

Thanks for the info, its a NEMA 17 geared at 27:1, way too much obviosuly from what your talking about. What you are saying makes sense because if I try to go faster than 5 mm/s the stepper motor usually stalls, gives taht whining noises but no movement. Maybe the DRV8255 drivers will allow a little more juice to be given to the motors, but in the end I have bought a nema 17 5:1 geared motor, sho

Re: Extruder feedrates maxed out somewhere? - 7 years ago

I am thinking that it is just the stepper motor itself, I change to 1/2 stepping, and it helped, but it it is intermittan, meaning it looks like it wants to go fast, because I set the acceleration to 10 mm/s^2 and it slowly accelerates until about 5-6 mm/s and then stops but the motor is clearly still trying because I can hear the whining noise. I maxed out the stepper driver voltage pot, and th
