Topic: pronterface control fail need help quick!

so since i have gotten my printer i have been doing a lot of prints but just yesterday i ran a print and after i went to lower the ed and instead of lowering it it raised it into the extruder and now when i go to print it seems to ignore the endstop and run the bed into the extruder and when i try to lower it it raises the bed still! please i need help quick.  i  have also tried repitier but it also just made the bed raise!

Re: pronterface control fail need help quick!

Since this is happening on different controllers could this most likely be a problem with the firm ware on the solidoodle itself

Re: pronterface control fail need help quick!

Weird. Have you tried resetting the printer?  Also make sure to redo you bed height check since it has been roughed up a little bit. Nothing got unplugged?  Maybe check your z end stop wires and the motor wires.

Re: pronterface control fail need help quick!

Ya I tried resetting the printer both from the controller and the back of it and from what I saw nothing was unplugged and by resetting the bed height you mean that when you raise the bed from the controller it hits the endstop and stops cause if so I have done that. Later I will try to download the firmware again to see if it will help. But if there is anything else that may help I will try basically anything

Re: pronterface control fail need help quick!

I'm betting the motor driver failed, or there's a bad connection in the step/direction path.

Can you swap the z driver and the y driver on the motherboard?

Good luck!

Agreed on the connection issue. If that's the case he could probably solder a little jumper on there instead of replacing it, no?

Depends on where the break is, but yes.

If swapping the drivers moves the issue to the y axis, then the issue is on the driver board. If it doesn't, the issues is on the Sanguinololu.

Re: pronterface control fail need help quick!

Sorry if i ask a lot of questions but I'm new so could you please give me a diagram or pic of what i would need to do. I'm confident in my soldering skills just I'm not that familiar with the solidoodle electronics.

First just swap the connections that are labeled on the board. Put the y where the z was and z where the y was. If you do this, does the z start going in the correct direction and does the y go in the wrong direction?

BTW, do these with small steps and maybe move the bed manually close to the middle first so you don't accidentally ram it into the bottom or the top. Also manually move the extruder to the middle.

Or by the driver do you mean the little chip next to were the motors plug in if so then i know what to do

Ok thanks so if i switch the places that the z and y are plugged in at and it switches to the y then just order one of those and replace it but if it remains in the z axis i will most likely have to replace the mother board.

Yes, or you'll have to troubleshoot the motherboard for a bad connection.

Don't buy one from Solidoodle - you can find them cheaper elsewhere.

Make sure you unplug bothe power 12v and usb power to the printer before swapping the plugs around... just in case smile

thanks i will make sure to do that

Re: pronterface control fail need help quick!

Thanks everyone it was just a bad driver i will be ordering 2 just in case something else happens!

Re: pronterface control fail need help quick!

You may be able to salvage this one using a jumper if it is working, but not sending the z down. At least it could work while you wait for your replacement.

Gonna be hard, since the A4988 is surface mount QFN.

Agreed, but may be fun to try.  I've done this before on surface mounted chips on quadcopters using a piece of solder as a jumper.  Teaching kids to solder solid state accelerometers leads to many a melted traces.

Re: pronterface control fail need help quick!

well i got my two replacements and tryed them but nothing changed it would still keep going up instead of down, so now im thinking its something with the mother board. and hopefully solidoodle will take a look at it or something since its not even a month old.

21

Re: pronterface control fail need help quick!

When you swapped the drivers, did the problem move to the other axis?

22

Re: pronterface control fail need help quick!

when i switched the place were the motors were connected it moved to the y axis but when i changed drivers nothing changed.

Ah! When you said:

"Ok thanks so if i switch the places that the z and y are plugged in at and it switches to the y then just order one of those and replace it but if it remains in the z axis i will most likely have to replace the mother board."

"places that z and y are plugged in at"

I assumed you meant the driver board.

If the issue doesn't swap axes when you swap drivers, then it's a problem with the motherboard or the ATMega. Sorry about that.

Re: pronterface control fail need help quick!

ok so i went to take the board off to get it preped to return to solidoodle if needed and realized that when solidoodle snipped the exsess leads off the back there was a small part of a lead jumping two of the points in the board so i removed it and hooked my printer back up and it seems to running. but before i start seriously printing again does anyone believe this could be the culprit?

We have seen this sort of thing before.
