My First Post.
Thanks for all the intel here on calibration issues.
I have had my Duo for 3 days and it has been an "Experience".
There is 0 support from XYZ Printing. The online site for Firmware updates is Offline and the support ticket page is broken and the Submit button does nothing on both IE and Safari.
I have emailed them.
Below is the content of what I tried to put in a support ticket.
Any advice from Forum members would be appreciated.
Cheers
Unpacked Printer
Downloaded test Print Job from Gallery Dual colour model.
Unable to update Firmware from Mac. Set up Windows to download firmware.
"says oops online service not available try again later". Been trying for 3 days same response.
Printed Test job and Extruder 1 had filament jam. Re loaded filament it was OK.
Extruder 2 then had filament jam. Could not reload filament would not extrude.
Unloaded filament and found that filament feeder had scratched the filament and could no longer pull the filament. Unloaded Filament, cut out scratched filament and re loaded.
It would then reload and extrude.
Printed test job again and had same issues. Filament would not extrude after contact with print bed.
Issue found. Extruder too close to print bed. Print bed blocks extruder flow and filament feeder scratches the filament try to feed until it can no longer get a grip on the filament.
Issue print bed out of calibration. Assume moved in shipment.
Ran Calibration utility to get reading on print bed.
Reported 164, Err, 62.
Cleaned contact point at calibration point 2 as per user manual. It did not fix the Err.
Adjusted print bed to calibrate. The is either an electrical or mechanical issue at calibration point 2.
I spent 14 hours and many calibration attempts to calibrate.
The issue is the calibration at point 2 will only make electrical contact if point 2 is 160 higher than point 1 and point 3. That edge of the print bed will only make electrical contact if angled up from rest of bed.
By moving the calibration nut by the width of one of the thread grips on the screw it will go from 160 to Err.
When the extruder attempts to locate the calibration point 2 it does not land on the surface but the edge of the calibration pad. Hence only makes contact when the edge is angled by greater than 160.
So it is impossible to calibrate via the calibration utility.
I did notice that the spring on the adjustment point for point 2 has a different spring tension from the other 2 springs. It is a softer spring and does not hold the bed very tightly as the other 2 do.
I then manually calibrated the printer at all 3 calibration points by hand, with the printer off and manually moving the heads and print bed the same way as the automatic routine.
I used a 100 feeler gauge to do the calibration. (On the assumption that the factory calibration was as advised in the manual as 100,100,100)
I then ran the auto calibrate to check the success of the cold manual adjustment.
It reported 101, Err, 96. The Err due to the issue with calibration point 2 described above.
I ran the calibration utility a number of times and these numbers changed but within +-004
I retried the print test and it now work as expected without issue.
The questions I have are.
Is the soft Spring the issue with calibration Point 2.
Is the print bed out of alignment with the Extruder mechanism causing it to miss the calibration point?
Will not having a saved calibration reference point cause me issue continuing with print operations?
Would a firmware update correct this problem. If so How do I perform a firmware update with the update service not online?
The software update site works OK for Windows but not Firmware.
For the Mac it does not recognise the hotfix for Mac OSX Yosemite. This has to be downloaded manually and installed.
Please advise the answers to the questions and what I should do next.
Cheers Brian Roberts.
