I have tried with temperatures from 160 to 210 with PLA also try to strude less plastics getting problems of structure but I still have the same issue. also I have increased the speed for movements and slow the speed of printing, I don’t know what else to do.

This is the test file I printed, i also tryed some more with the same results:

Could you tell me what brand filament you're using and any specs you have for it? Do you have another brand/color that you can try?

I found that this boxzy is unable to do the retraction, maybe this is why this stringing ploblem is happeing, i have the retraction option active and i have changed the values some times a little without any change.

Im thinking return the printer.

Regards.

Hi Felix, BoXZY will not provide a replacement without troubleshooting the issue first, as its likely related to settings and not the device itself. You can contact Support@BoXZY.com, but I will also try to resolve your issue. First, please heat your nozzle. While hot, enter G90 E0. After you have sent that, please enter G1 E-5, does BoXZY push filament backwards out of the filament drive? If it is reversing properly, please increase your print temperature to 216C for your next print. They have found that works best for some of the off brand plastics. The team highly recommends stock retraction and temperature setting with Hatchbox brand filament specifically. All other brands will require additional tuning.

Effectively, I made a design of experiments and change the printer to a room with controlled temperature, now the printing is acceptable on quality, controlling the setting, Retraction and Z lift was the key, I still have some stringing but it’s acceptable. Also checking the extruder under microscope I found a little damage on the tip I thing maybe is a leaking issue.

There is any official supplier for Mexico? I but this one on Newark but they do not have spare parts, I want to buy another extruder to check if that solve the situation but is difficult find one in Mexico.

Was there not a spare nozzle in the fix-it kit provided with the machine? You can purchase a replacement here: https://boxzy.com/product/nozzle-assembl...

No, this machine don’t have any spare. I will buy one new and try to improve the printing, now the machine is working a lot better only some minor leakage and sometimes minor stringing, but I have very big values of retraction 8mm with 70mm/s with 0.3 Z. that is the only way to get good printings.

Thanks for the support im ver happy to see that the forum is very helpfull.
