We have been using an UPBOX+ for over 3 years and it has been super reliable and produced thousands of parts, so we decided to compliment and expand with the UP300- Tiertimes replacement for the Upbox+.
直接开箱即用，易于z轴错误，在z轴移动时非常响亮。
we contacted the supplier immediately and after doing all the possible fixes that they emailed us to try, no success.
Eventually they had the printer picked up by a technician and it was “fixed”, about a week and a half later.
但是首先打印，同样的问题。
It has now been over a month since our purchase and to say we are dissapointed with this printer is an understatement.
Very long delays in communications from the supplier to try and resolve this, we wait a week for a response to questions and emails about what they are doing to fix our printer.
Basically we have now had a printer that doesn’t print for over a month and no confidence in ever having this issue resolved.
Perhaps Tiertime can apply a little pressure from above to the Australian supplier?, as I’m just becoming more and more frustrated every time I look at this printer sitting on the desk.
它足够糟糕的是，它的错误直接开箱即用的......但没有明确的方式，没有关于所做的事情的沟通，并且不希望随时获得这种修复的希望超越一个笑话

Hello,

We are looking into this ticket, we think the Z axis is moving when it is not suppose to move.
very rare issue, would share your tsk file that causing this problem? I suppose you are using UP Studio for slicing?
还尝试再次运行AutoLEveling并重新打印。

Latest version of Up studio, latest screen version…screenshots of the table level accuracy,etc.all this information is supplied with the ongoing ticket history.
TSk file was given to the supplier previously.

Its not the z axis moving when its not supposed to…its the z axis NOT moving when its supposed to.
from day one it has been sticking and loading up.

Luckily we have another printer right beside it, an UpBox+ , so we can print and compare things between the two.
The exact same file that the UP300 fails on, prints on the UPBOx+ perfectly.
if we didn’t have that to verify with we could spend months chasing down software issues that are not the cause.

Definitely not a software issue, as with both printers turned off side by side, the UP300 takes around 3 times the force to manually lift Z axis by hand compared to the UPbox+.

Autolevel works fine (so far), but cannot set the nozzle height or print. the axis jams and the motor loads up or skips before it can get to that stage as per the video of the issue I supplied last week.
Link to video is in the ever growing ticket history.

你可能尝试了干净的旧润滑油the Z axis lead screw and then apply new lubricants. use the software to run the platform up and down for a fews time, then see if the Z axis become easier to move.

This was done by the technician the first time the printer was taken way for repair, and I have wiped it down again since, no result.
I cannot spend much more time trying “fixes” for this printer, I have work to do and so far we have spent in excess of $1000 in my time alone trying various fixes…
也许我们可以为迄今为止和未来时间花费的时间发票给供应商？由于我们花费了超过一个合理的时间，作为客户协助整理一个显然制造缺陷的问题，而不是我们的财务责任纠正。

＃6

not really my business, but that is probably not the kind of service people expect when buying a $2000+ brand new 3d printer. I’m pretty confident that that statement alone will cost you more than replacing the printer (which has the added benefit of Tiertime being able to inspect the printer to find the cause and improve…)

Some further information to hopefully further any progress in fixing this issue.

This morning I measured the difference between moving the table manually in the Z axis on both machines.
UPbox+= 4 kg - 4.5 kg of force
UP300= 15.5 kg -16 kg of force

As yet I have not had any further contact from the supplier about fixing this printer, was emailed last friday about the best time to be called about collecting this printer to get it back to the technician, I replied immediately that Friday, Monday,Tuesday…ANYTIME would be good !..but no further communication or contact after 6 days.

我们的替换打印机今天到达：脸红：and is already printing away, so far its all good with no signs of the issue we had with the previous printer.
Some things are a little different, maybe this is a later version or batch than our previous one?..touch screen is far more responsive, there is virtually no motor/belt noise compared to the other one and it comes from the factory with a longer spool holder that can take wider 1kg rolls than UPFila.
Straight out of the box…the table was level within 0.04mm…well done Tiertime…I hope this printer is as
robust and does as much work as our UPBox+ has done.
