Re: LIN_ADVANCE = better extrusion control

You should be able to change it in one of the configuration headers. Search for 0.02 The SSH method definitely works though, might depend in your other settings how much it effects print speed. You can send any gcode you want using SSH, even during a print. I've found it really useful for adjusting...

Re: LIN_ADVANCE = better extrusion control

FYI, 1.1.9ABH also has Junction Deviation enabled, which replaces the old Jerk settings. The default is 0.02. Try 0.05, and WOW I can print fast. Set with M205 J0.05. Adjust it during the middle of a print to really see the difference. (SSH in, "echo M205 J0.05 > /dev/ttyACM0") Edit: 0.08...

Re: E3D v6 Adaptor

I've now solved my problem. I replaced the thermocouple and now everything is working again. I also installed the 40w heater and can now print at 150mm/sec. I have found that I need to increase the temperature to print that fast. So the first layer is printed at (using eSun PLA+) 215C and then the b...

Re: E3D v6 Adaptor

Thanks for the responses. I don't yet have an extra cartridge, but when I do I will check with a meter. Since I wrote the above, things got worse. The hot end is now reporting no rise in temperature even when very hot. So maybe it is a bad thermocouple or amplifier. No time to check until Sunday or ...

Re: E3D v6 Adaptor

Using E3D hot end on N2 with BondTech extruder. I'm reading a temperature difference of 24% at any temp between my set temp and the temp I read with a K-2 thermocouple meter. So at a set temp of 215C I get a display temp of 215C but a meter read of 190C. I'm placing the probe behind the silicone boo...

Re: Change dip switches to 1/2 step for extruder?

Thanks for answering Ari. I did try and it worked well. Less noise and no noticeable heat. I also changed out the full size stepper for a pancake one and it responds very quickly compared to the larger moment of the larger stepper. I set the steps to 1/4 and reduced the espets from 2680 to about 680...

Change dip switches to 1/2 step for extruder?

Due to the extruder I am currently testing, I have to set the esteps of my driver to 2700. My thought is that if I used 1/2 microstepping instead of 1/16, there would be 1/8 the number of impulses arriving at the motor and that would reduce noise and heat -- probably mostly heat. (I am hopin gnoise ...

Re: Bondtech and 3dsolex nozzles

I seriously doubt that the stock hot end can deliver enough BTUs to successfully print with a 1.2mm nozzle. I was trying to print ABS at 100mm/sec with a stock plated .6 nozzle and the hot end could not keep up. However, I am surprised that you can print with 1.0mm. That's cool.

Re: Bondtech and 3dsolex nozzles

I have revisited these nozzles now using Marlin 1.1.9 from ABH and version 1.5 Linear Advance K-factor. I have been able to successfully print at up to 200mm/sec using 0.6 nozzle mounted on E3D copper block at jerk up to 15 and acceleration of 3000. I have not tried to go any faster -- due mainly to...

Re: ABS and HIPS new settings since 3.3.0 update?

I have found the solution to flowrate/multiplier in IM: Go to the Advanced tab... see below. Then set all other flowrates in the tempalte to 100% to get the 95% that I have in my example. Doing this I got a 25mm cube to print 1.2mm walls.

Re: ABS and HIPS new settings since 3.3.0 update?

I'm finding in IM 3.3.02343 that adjusting the flowrate in the filament form does nothing. I've been trying to calibrate filament to my new extruder and this has been sending me around the bend. I am now doing it in the template, but I do not see a way to set the flowrate for the walls. Is there one...
