Can anyone help me figure out why my extruder is skipping like this? [www.youtube.com] This is on a Prusa i3 with Marlin Firmware on a MKS Gen2 v1.1 I am brand new to printing and noticed that when I tell the printer to extrude 100mm it only moves the filament about 55mm, so something is wayyy off.

It is at .856 V right now, but I am not sure what to set it at
. What kind of noise will it make, will it be different from the noise it is making now?]]> Grifftech Printing Sun, 10 May 2015 14:33:12 -0400 https://reprap.org/forum/read.php?262,507059,507389#msg-507389 Re: Can anyone help me figure out why my extruder is skipping like this? https://reprap.org/forum/read.php?262,507059,507389#msg-507389 lunarkingdom Printing Sun, 10 May 2015 13:46:38 -0400 https://reprap.org/forum/read.php?262,507059,507119#msg-507119 Re: Can anyone help me figure out why my extruder is skipping like this? https://reprap.org/forum/read.php?262,507059,507119#msg-507119 Grifftech Printing Sat, 09 May 2015 19:04:58 -0400 https://reprap.org/forum/read.php?262,507059,507107#msg-507107 Re: Can anyone help me figure out why my extruder is skipping like this? https://reprap.org/forum/read.php?262,507059,507107#msg-507107

it's not filament slipping because the shaft of the motor is twitching too. To me it looks like you need to adjust your stepper driver current. It looks like it might be a bit low. I don't know anything about your electronics, but the typical stepper driver has a trimpot which you can use to adjust this.

I have the MKS Gen 2 v 1.1 with RAMPS 1.4. How can I find out what voltage the pot needs to be set at?]]> Grifftech Printing Sat, 09 May 2015 18:25:06 -0400 https://reprap.org/forum/read.php?262,507059,507074#msg-507074 Re: Can anyone help me figure out why my extruder is skipping like this? https://reprap.org/forum/read.php?262,507059,507074#msg-507074 jbernardis Printing Sat, 09 May 2015 15:48:14 -0400 https://reprap.org/forum/read.php?262,507059,507059#msg-507059 Can anyone help me figure out why my extruder is skipping like this? https://reprap.org/forum/read.php?262,507059,507059#msg-507059 www.youtube.com]
