I have run into this problem a few times but not to this extent. I am trying to print a small toy car body. In hindsight I most likely should have orientated it roof down but at the time it seemed as though a vertical orientation would result in less support. I think the images attached speak for themselves - the main issue is the horrible surface quality at the back of the car. Secondly the slightly uneven layers near the front door/pillar.
I am printing in ABS, medium infill, 0.09 layer height, Speed Normal, Support Angle 10 deg, Fan Auto. Z-Suite 1.4.1, firmware 1.0.5
If anyone has any suggestion, advice, etc. I would very much appreciate it.
Forgot to mention - my M200 is about 2 months old.
looks normal too me, very hard for FDM printers to print at the place you are having issues.
I would say angle the model at 45 degrees. With this i think it will need more support but the surface finish should be better. And after printing the model at 45 degrees you could get an even better finish with acetone treatment.
Thanks for the help guys. I tried printing again as suggested (car on more of an angle with 20 deg support) and the overall surface quality is much better. But I am still having the slightly offset surface issue I also spoke about (see attached). It's pretty obvious on the side of the body. I'd be happy to hear what may be the problem. Mostly just wanted to say cheers for the advice and show the results of another print.
It's no problem, I had machines ready to print. Great thing about M200, you can start the print usually walk away.
Oriented vertically so it would finish by tonight. The backside looks poor (kinda expected), similar to your vertical print.
I don't have offset/banding on mine. The offset on yours almost looks like the axis maybe slipping or something. Check the set screws on the xy axis / motor pulleys are tight and the belts tight. Also when adjusting platform, start off with the adjust screws as low as possible, if you are high on them the platform is less stable and can shift during a print. After checking those, try the settings below.
Z-SUITE 1.7.2.1
Z-ABS, 0.09mm, low infill
FW 1.05
Everything else default:
High quality, normal seam, 30 deg support, auto fan, smart bridge on, support lite off (would have turned on but forgot)

Bold highlights settings differing from yours.
Thanks again ChunkyPastaSauce! Your print looks great. So the rear wasnt much better then my result?
I did the X, Y and Z maintenance as per the Zortrax site this morning. Everything was tight. I also cleaned and re-applied grease to the rails. The build platform is as close to as low as I could get and perfectly calibrated all bar the centre which is out by the smallest of margins.
So I'm about to setup the body again following your settings although I will orientate on a angle again as its the best results I have had with it. Hopefully the banding and offset will be no longer there.
Ok, printed again. Seems like something I did to the printer yesterday may have helped with the surface offset issue. I did remove the motors and re tighten the belts although they were tight before removal. I checked all the screws etc. Re-applying supplied Zortrax grease to rails/guides. I don't understand the colour/hue difference in the material however.
Any thoughts on the BEST grease/oil to use for the guides?

As far as the color issue, I get that too on some colors. For lubrication I use Super Lube synthetic grease. Printer is three years old and still going strong.
