[Solved] New Mini .. Not a happy camper so far ..  

RE: New Mini .. Not a happy camper so far ..

haopend to me too, the cable of one of the x axis stepper motor was wraped around the stepper motor, therefore it could not go further up. maybe this happened to you tu, and the cable got torn out the board and pulled some more cables out. checked for that?

RE: New Mini .. Not a happy camper so far ..

No .. thats not it .. checked board and connected but hotend heater connector is on an angle .. not stright up and down.

RE: New Mini .. Not a happy camper so far ..

Still waiting on support ..

RE: New Mini .. Not a happy camper so far ..

Well looking like a bad heater cable and checking on why Z Axis is not going to top ..  seems to be a software rather than hardware issue ..

RE: New Mini .. Not a happy camper so far ..

So far looking like maybe a defective Pinda, Bad heater cable .. or  figuring maybe a board problem .. ah well .. support is being super ..

RE: New Mini .. Not a happy camper so far ..

New parts on the way .. Support was super as always .. New product, do not really mind the growing pains, as I learn from them as well, but when the support is this good .. it is all ok ..

RE: New Mini .. Not a happy camper so far ..

Prusa support get very busy sometimes and you have to cut them some slack, but they have never let me down and always go above and beyond. Sorry you had problems but glad you got a result.

Which parts, specifically ?

The cable for the heater has varying resistance from 27 down to 16 and bounces around s0 they are sending a replacement, My hot-end heating is inconsistent and works sometimes and sometimes not. Acts like a bad connection.

With the initial XYZ calibration, the Z axis starts off with a check mark and never even attempts to go to top, it just does the X and Y axes. When the Z tries tries to home it just homes to wherever it is and calls it a day.. They diagnosed it as a bad Pinda so are sending a new one.

That's all I know so far.. It is covered and off to the side for now..

RE: New Mini .. Not a happy camper so far ..

Mine does this if the ambient temperature is low.  I think it's seeing a temp under 15C and assuming MINTEMP before trying to put any heat into the hot end.  It should probably be turning on the heater for a second or so before checking the temperature, if it's not already.

RE: New Mini .. Not a happy camper so far ..

That's not it for me .. Temp is 21-22 and it will work and then it won't, no seeming rhyme or reason, something with the connector or cable ..  Z axis stuff is my major concern .. seems very weird ..but hey, good news is .. it didn't kill my dog .. bad news, that's the only good news so far .. will wait for parts and give it another go .. sure it will work soon .. so just smile and waive ..

RE: New Mini .. Not a happy camper so far ..

Gerry try one thing please.

Turn printer off and turn the z axis completly down a mm away from bed. Then try again calibration. Thought about and i guess that was the problem i had. I guess the firmware shuts down if in calibration prozess after few cm the pinda dont show surface. Maybe to avoid crash when pinda isnt working

I think the cable problem was at my mk3s build.

@jameswilddev

If that were the case, wouldn't you see a MinTemp error?

RE: New Mini .. Not a happy camper so far ..

@pingu

Hi .. tried that .. took the pinda down to one tie height and then checked nozzle, two pieces of paper or so .. so should be fine.. Tried the Wizard again and the Z axes goes up about an inch.. buzzes loudly for a minute and ten just stops .. will try the new Pinda when it gets here and hope that fixes it but I am uncertain .. 

RE: New Mini .. Not a happy camper so far ..

Just got the email form Prusa about the new release of firmware 4.0.01 and downloaded and flashed .. but sigh .. no difference for me with the Z issue.. Maybe it is a bad Pinda .. Someone else had a similar issue with hotend E1 error and also with  a slightly offset connector; he pushed back into place and no more error.. I did the same and have not had the E1 error again but the Z homing issue continues to turn the mini into clutter on my workbench ... Maybe it is also a bad connector on the board .. will check ..

RE: New Mini .. Not a happy camper so far ..

Nope .. no difference.. It bothers me that the Z axis always starts as checked when running the wizard .. Not sure if that is what is supposed to be the case .. It only moves the X and Y axis during the axes test .. Homing is move up a bit and stop .. Wait for package to arrive and take it apart I guess .. 

RE: New Mini .. Not a happy camper so far ..

Does the Pinda light up on the Mini as it does on the MK3S? Mine does not ..

Mine's got a red light on the top.  It's quite faint.
