Incredibly slow print speed

GG

Hi Chaps, finally got my corexy printer working and new "genuine paneldue " after ali express refunded my faulty clone. Im running the duet2 ether, I purchased simplify 3d and run test print but got bad warping with pla , with same hardware as before which never warped, so I went back to Cura slicer to test same print, problem is , printing is now incredibly slow ??? cura slicer says 50mm/sec but printing is more like 1mm / sec any help appreciated.

alankilian

I've made the mistake of having the speeds in Simplify 3D set to mm/minute instead of mm/second.

50mm/minute is about 1mm/second.

Is that your problem?

GG

@alankilian Thanks for reply this test piece was sliced in Cura and Ive just checked and it is set at 50mm / sec in cura so not sure if thats the answer or no

alankilian

@GG Post both your GCODE files. That will tell for sure.

Or at least one G1 move with an extrusion from each file.

Phaedrux

I would bet that your cure slicer start gcode has some speed limits defined which are limiting your speeds.

Hi this is the cura gcode , having trouble getting simplify 3d code

you are setting the speed to about 8mm/sec here

Delete the M201 M203 and M204 lines and restart your printer

alankilian

@Veti You beat me to it!

What a great community we have here.

Also change your gcode flavour to reprap

Delete M205 as well.

GG

@Phaedrux I removed the sugggested above gcode from the start gcode in cura in machine settings and akso changed gcode flavour to reprap but still runs at snailpace

Veti

@GG

did you restart the printer afterwards?

Phaedrux

Post your config.g as well.

If you post your GCODE we can take a look again.

This is the curent config g and yes I did restart machine, just tried it again with same result. Strage thing is the printer worked fine when slicing with simplify 3d but the print warped and the vertical sides of the cylinder were wasted in the middle , I ve never had warping before with the old cheapo mini chitu board ??? atached below is current start gcode

If this is the same gcode file as before you would need to delete it and re-slice after you've removed those lines from the start gcode.

@Phaedrux that seemed to solve the speed issue, so I printed same cylinder shape but the print quality is awful, as I saids the vertical sides of the cylinder are waisted in the middle , scalloped I guess when they shoule be strait, the old mini board used to print these fine, coule it be the mother board the problem I wouldnt have thought so. ???

M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z1000.00 E1200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E250.00 ; set accelerations (mm/s^2)

In your config.g file change the Z acceleration and jerk values to be a bit higher. As they are now they would cause some problems with mesh compensation.

Try
M566 Z60
M201 Z200

Can you share a photo of what you mean about the quality issues?
