Printer stuttering during prints (Page 2 of 2)

That is does but unfortunately you may be SOL... This screams bad drivers to me and since yours are soldered to the board there is no way to test or replace them. If you had an older board they are in sockets and you could move the Z and extruder drivers to the X and Y and see if the problem still happens.

XYZ has the digital current control on their boards set way too high and it is causing the motors and drivers to be driven too hard. The motors are excessively loud and get way too hot and the drives also get way too hot. I lost two drivers on my 1.0 and ended up having to take out the stock controller and put in a RAMPS 1.4 controller.

If the current is adjusted properly the motors will just feel luke warm after a 5 hour print and you cannot even hear the machine running being in the same room. The fan on the power supply will actually be the loudest noise source if the machine is setup right.

No guides as of yet. If you went RAMPS  you would need a new LCD as well as three optical or mechanical end stops. The stock parts are not compatible with aftermarket. You might be better off just parting this one out and getting another or different brand printer unless you get lucky and find the issue. I still think its in the wiring for the motors and/or endstops. But that is tough to isolate.

Ok, interesting development here. I got a good print, near perfect with no cleanup.
I try another print afterwards and as my printer was heating up the bed and extruder, there was a loud band and now nothing. I cant get any power at all, I'm assuming my power supply blew.

Is there anyplace to get a replacement? Or something I can do?
Little disappointed since the printer is only a month old, lol

Hi MJAussie360, I replaced my davinci 2.0 psu (first gen with removable stepper drivers)

A couple things I've found that you might find useful. I'm running luc's repetier 0.92 on a 1.0 and 2.0 and repetier on my 1.0 with a ramps and e3d.

First, if it wont turn on, that's almost definitely the psu, but I think you can test by using a regular ATX PSU. Do your research, I don't want you blaming me if something goes wrong, but the connector for the davinci board with only black and yellow wires was the same as the 2x2 CPU plug from my ATX PSU (make sure all the wire colors are the same) and I believe the red/orange/black are standard as well, but I did not need them in my case. I was able to temporarily use an external PSU to troubleshoot.

If that solves your issue, then you definitely need a new PSU, and I was able to use the "Solid Gear Mini ITX 320-Watt Power Supply" (SDGR-FLEX320) that kev0175 as a drop in replacement: (http://www.amazon.com/gp/product/B00A8Z … PDKIKX0DER).

Recently I had an issue like yours that I never found a (definite) solution for, it just worked itself out. Every movement seemed to have no acceleration. To this day I think I may have manually changed acceleration to something crazy, causing the issue. I tried an auxiliary PSU like I described, and already had heatsinks on all the steppers. I even replaced one of the steppers with a RAMPS-sized 4988 (I'll post a pic, it's easy to patch it in with little/no modification). But the only thing I can figure fixed it was running one of the stock files from the SD card that I think might have somehow loaded safe defaults.
