Help everyone!

I’m giving up on velleman support they just can’t answer my problems they keep telling me the same thing just in a different way i have tried everyhing that all aksed me but nothing helps. Small areas on my prints gets all blobby and it can’t bridge correctly.
So anybody out there please help and see if you can print this: https://www.dropbox.com/s/0m5z6emn0zjqdq5/Failed%20print.gco?dl=0 and send me some pictures of it i would really appreciate it!

Pictures of my print:

Heres my printed copy. Mind you :
It is abs and I changed the print temp to 220 C since I know it works at this temp.

I wonder what slicer you use since there is a command “M106 Fan on” which I have never seen when slicing with Cura or Slic3r. What it does is to run the fan while the extruder is heating up so the heatup is extended from about 3 minutes to about 10 min.
Do you print with abs or pla ? It seems the suggested 210 C in the gcode does not suit either.

My only mod to the printer that might make an improvement is I added the fan duct found on thingeverse.

Have you got head lift cool checked in the Cura config? It looks to me like it’s wrecking the small areas as it’s dragging them around while the last layer is still hot.

Hi, thank you very very much for printing it i really appreciate it!!! :slight_smile:
I’m using Cura Engine in velleman’s repetier host so thats where that code comes from
and i am printing with PLA and it should be 210 C?
And the cool head lift are off because else it would make the top layers ugly.
When i print with support! it is almost impossible to remove do you have the same problem?

Thanks,

Try Lower temperatures. 200 and 190.

Your welcome.

Yes I suggest you lower the temperature to 190° if you use Vellemans PLA. If you use something else, start at 200° and work yourself down.
Also make sure the in the gcode it is the correct temperature. Within the first 10 lines there are 2 temp settings. One line could be " M104 S220 " if it is not the temp you have set in the configuration you can change it directly here in the gcode to " M104 S190 "

I also suggest you delete the line “M106 Fan on” since it only delays the heat up process.

I have not printed so much with support so I cant give you any feedback on that.

You shouldn’t need to do either of these. In RH, on the Cura config tabs, you can use ‘Save As’ and make sure you select the filament settings you saved for the nozzle your using. It will print at the temperature you set. This is the best way to experiment as you can keep your settings easily.

I also wouldn’t delete that fan command in the gcode, it’s there for a reason - it prevents excessive heat travelling up the PEEK insulator and softening the PTFE tube, particularly at higher temperatures, which can lead to thickening of the filament at the end. You can lower the fan speed however during warm up, however I seem to vaguely recall that Velleman recommended you don’t go below 30%.

@bomfilur - you might profit from reading through some of the old forum posts. You will see that most users have found the 210C default temperatures for PLA is too high, it has been widely discussed. You might also want to reduce your flow rate to ~75%.

If you change your support type to lines instead of grid it is much easier to remove.

Your absolutely correct, in theory.
However it happens to me frequently that the temperature, even when saved, does not come along to the gcode.
I have made a rule to always chech the gcode for this.

Presumably you are correct here too.
However I have never had that particular line of code included in my gcode. Regardless of slicing with Cura or Slic3r.
