So I purchased the k2 and for the last two weeks it has been printing awesome… no issue, everything coming out great.
Then yesterday I started a print and noticed the first layer looked terrible. I had not moved or changed anything. Re calibrated and started again. Still looked squashed so I manually set the z offset on the print to drop the plate. The print finished fine. Decide to have a look and found the following issues.
- Hot end screws that hold the heater part to the heatsink were loose. Two smal screws if you look up from nozzle.
- As per the troubleshooting guide I checked the xaxis rail and the screws were also not tight.
Tightened everything and recalibrate. Print starts out great but during print I notice the nozzle scraping the model, finish print after dropping z offset again.
Heat up the nozzle and I see that it is also loose. Tighten up, check all the hotend screws again and start new print.
Touch wood printer is running a 25 hr print and the issues seem gone
So very long winded, but the machine worked 100% out the box.
So I would suggest every couple of days/ prints to check these things as a maintenance task so that you do not pull your hair out done the line.
