Finally got the D9 level and printing!

by stugpanzer

I have been struggling with getting my printer properly leveled. I thought I had it once but I didn't. I ruined one of the magnetic build plates. Now I finally have it dialed in.

The first thing I did was to disassemble the whole bed assembly. I verified that the heatplate is level and I verified that the steel plate is level. My issue was all around the crappy bearing rollers. When I received my printer, like many people, three of my bearings were pushed out of the roller. I did press them back in but they kept popping out. I decided to order Xtreme Solid V Wheel kits: https://www.ebay.com/itm/20-Kits-Xtreme-Solid-V-Wheel-Full-Kit-for-20mm-Extrusion/123263651872?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 After installing them I then completely tightened all four bed leveling screws. I should say here that I am running v164b firmware. First be sure to level both sides of the Z-Axis manually with a ruler. I ran the autolevel routine by stopping at the first stop in the middle of the bed. I then moved the print head to all four corners and manually leveled. Once I had that I then tried autoleveling but the nozzle was too high so I had to adjust the auto level sensor. I did that a few times until I was satisfied that it was level and that the nozzle was at the perfect height. I tried printing but it seemed I was having a nozzle jam so I went ahead and replaced the nozzle. Finally I was able to print. I printed this calibration cube: https://www.thingiverse.com/thing:1586206 and it came out great! I have never printed ABS but I will be printing a couple new cooling fan shrouds and then get ready to do a large print. I feel I need to do that because from what I read, this printer struggles with large prints as the cooling is not adequate. The two I wnat to print in ABS are https://www.thingiverse.com/thing:3044199 and https://www.thingiverse.com/thing:3012498.

I would like to suggest that Wanhao make a connector for the heat bed and ship with it NOT installed. That way the bearings and/or the bed won't get messed-up in transit Let the consumer assemble the bed.

Restart after power out problem.

by Geart

This printer has a big problem, if you continue the print after power out the print head goes to its home point first but if the printed object is big enough the middle bar where the printhead is attached to will get blocked by the printed object.

Essentials for good prints on the D9?

by stugpanzer

I am still getting the D9 up to standards for quality but it is still not yet as good as my CR-10. What are the essential things to do to really make this printer work well. I am already looking at replacing the V-Wheels and bearings but what else. As I said I am getting better quality prints out of my CR-10 using the exact same gcode generated by the Wanhao Cura software. The one thing I seem to be struggling with is perfect bed leveling and having to fuss with that.

Printing my first large print.....

by stugpanzer

I am printing a large print that will take about 5 days to complete. I have everything dialed in for this print and want to see how the printer handles it. I do see some concerns which might be related to parts cooling so will give a fan duct part a try when this print is done.
