Printing on 1600Yx1000x1000 printer Dowell 1610-10 DM
Cura Version
5.7.1
Operating System
Windows 10
Printer
Dowell 1610-10 DM
Reproduction steps
Using .8 mm nozzle. Layer height 0.4 all layers. Z hope 1.0
Actual results
Fist layer prints, .4 layer height. Second layer only .2 higher and causing nozzle to block. ;LAYER:0 M106 S153 G1 F600 Z1.4 G0 F6000 X127.593 Y146.489 Z1.4 ;TYPE:SUPPORT G1 F600 Z0.4 G1 F2400 E0 G1 F3600 X115.864 Y157.183 E2.11166 [Z0=0.4 as set]
LAYER:1 M106 S255 G0 F7200 X212.638 Y251.697 Z1.8 ;TYPE:SUPPORT-INTERFACE G0 F4800 X212.638 Y251.697 Z1.6 G1 F600 Z0.6 [Z1=0.6 should be 0.8 Jamms the nozzle and stops printing]
Expected results
Normal printing adds 0.4 to each layer.
Somewhere betweent the Z hop of 1 mm and the next layer it forgets the Z number.

Thanks for the report. I'm not able to duplicate this and there haven't been any other reports about layer heights being wrong.
Please include a project file ("File | Save Project") so we can see your settings. You will need to zip the file and post the zip folder here. If you can't share the specific model, then use another model.

What I think is happening is the Z for the supports is .3 lower than the body of the print. So when it finishes the Z level for the supports, it hits the edge of the main print and is only 0.1 high causing the filament to jamm. This is what I think. I am having trouble removing the supports. So, I thought that .3 would be OK with some sag as the body line of it prints across it. Jim Arjuna HavenMade

We ask for project files and the Cura.log file and (occasionally a Gcode file) so we can analyze them. The files need to be zipped (Github rule) and posted directly to the site and NOT via email (Github rule). If you want an investigation into why you are getting the results you see then post the files. Without them there isn't anything I can do. I would need the original gcode file and not one that you have altered.
I changed my printer to a 0.80 nozzle and a 0.40 layer height and the Cura gcode was exactly correct. But that was with my settings. I need to see your settings (project file). As far as the gcode file goes, I've been working with gcode since my freshman year in college in 1969 and I'm pretty sure I'll be able to read it myself.
Cura never splits layer heights for any reason. With your layer height at 0.40 and the airgap over the support at 0.30 then Cura will determine that because the airgap is less than 1 layer that the airgap will be 0 layers. That would make it difficult to remove the support because without any airgap, the support becomes part of the model.
I found an older version that does not do this. It keeps the supports the same level as the part. Then later adjusts to allow separation of the parts.

I wanted to have the space between the part and the supports at. .3 mm. Because My first part with .1 mm was impossible to remove the supports without a chisel. On every "; LAYER:" there is a change to print supports lower. but then the print head does not RISE up to the .8 for the second layer and consecutive layers. It triest to print a .1 layer height with an 0.8 nozzle, going at 60 mm per second with a volcano nozzle. It jamms the filament, every time. The way to fix this is to adjust the final top layers of the supports to the .3 difference. I don't care about some sag I just want the supports to come off without using a hammer and chisel. I first printed this huge part, reduced to fit, on a 400 mm printer. But with a LARGE nozzle and the speed and heat needed to print faster than 2 weeks, (the first print took 14 days) I put a volcano nozzle and heat block on. It prints fine at over 32 mm, cubed per second. The 5.7.1 version is good except for this problem for me. I went back almost a year to an older version that doesn't do this. It remains at the .4 difference on every layer. The file sent here is from the Dowell version.

I'm going to go ahead and close this as I have nothing to investigate. I hope you understand.
Every time after the first layer it jams. It rises about .1 mm instead of the .4 mm layer setting. And it puts a .3 Z height lower on every layer.
