Clicking from Z axis


#1

Hi All,

I've got a problem in the newer of my 2 zortrax's.

I've filled out the form already, but just hoped someone can point me straight here.

My Z axis is clicking loud enough to hear as the platform raises, approximately 1 click per second.

I can't hear whether it is coming from the z screw bearings or the stepper motor at the bottom of the shaft.

It is leaving marks in the print now, as per the picture.

I have greased the z screw which seemed to make no difference.

I loosened the clamps on all the Z axis, as well as the coupler to the stepper motor, then slid the platform up and down manually a couple of times before tightening it all up again.

This improved the noise greatly, but it is coming back again.

Can the ball screw ball housing be dismantled, cleaned and regreased?

Is there an issue with tightening the mounts on the bottom Z axis stepper motor? I can only see 2 screws through the floor that mount it.

Any help would be appreciated, as I'm home with time to fix it now.

The situation with this issue is now becoming amazing.

I lodge the form with support, only to be told "no warranty outside EU", go to your Australian reseller.

As I have no warranty, I dismantle the ball screw and find a couple of little pieces of stainless steel in the works, obviously not washed out during manufacture.

Reseller agrees he will cover it or at least help out with the part and lodges his own request with Z....and it all stops. No answer to him yet.

The thing that is really peeing me off here is not that the part has failed, not that there's no warranty, it's the fact that they don't just bill me for the part and get it away urgently or send it to the reseller.

As I don't have a warranty, I'll pay for the part and fix it myself.

I've been a technician in remote Australian mines and oil rigs for almost 20 years, it's not a difficult job for me at all..

At least Chris has finally answered a PM, and I've relayed all this, but in the meantime I'm 50% out of business.

Zortrax:

What on earth would be wrong with just saying "sorry no warranty in Australia, but we can invoice you by paypal and get the part away tomorrow by DHL"? Would that kill you?

I'm certainly not surprised by no warranty...no printer manufacturer honors warranty.

But they will all sell you the part!

That's where this is just getting wierd.

Talking to myself, but have to be fair and update this.

Zortrax has offered to send me the part at my expense, and I have accepted.

It was expensive and I'm not totally happy about paying for it when the machine is 2-3 months old, but I need the machine working for my business.

I am a little shocked that there's no warranty on an expensive item like this, but it's no surprise after buying other printers.

I think that Zortrax should do a "parts only" warranty for countries outside the EU, with the reseller in that country verifying/authorizing each claim.

As it stands I certainly have a case by Australian law, but I'd have to attack the reseller, and I don't think that's fair in this case.

Thanks to Chris for getting involved and speeding it all up a bit.

Hello. I have the same problem. It seems to come from the 4 small screws that are fixing the bed onto the Z-Axis ball screw.

You mean with them being too tight?

Hello Hobbymods.

No they were too loose.

I tightened them, now it's OK.

Hi. 

I have exactly the same problem with the clikcing sound from the lower bearing of the z axis. I didnt have any problematic printings so far but this sound was very frustrating. I desided to loose the four screws that holds the lower bearing to the body of the printer and I move the platform up and down to find that there is no more sound from the bearing but the bearing moves left and right when the saft is turning. It seems that the shaft is bended and causes stress to the bearing every time it turns. Today I will try a print with the four screws of the lower bearing loosen. If there is no problem in the print quality I will let them loosen. If not I dunno, I’ll think of it later or maybe I’ll give a call to the support team and wait an answer from them.
