NVM I'm using Macros to set Flags for Nozzle size and Hotendtype and conditional Gcodes in the filament config.
I think it's more intuitive I can rename the Printer with
M550 P"Apex Pedator 0.4 HF PETG"
to make sure the correct settings are loaded
I'm using the Filament profiles while they are very useful there is a slight annoyance if you have many of them.
I'm setting PA , Retraction, Nozzle Diameter, Temperature and Hotend type (Rapido HF vs UHF)
The Problem is i that I have to name my Profiles like this:
0.4 UHF PETG
0.4 HF PETG
0.8 UHF PETG etc.
Because the Settings change depending on the material, nozzle and Hotend type, it gets a little bit overwhelming.
It would be really nice to have them organized in Folders for a better overview.
I've got an Orbiter 1.5 @24V LDO-36STH20-1004AHG
Jerk 1800
Accel 6000
current 750ma
it's working like that for at least a year no problems yet. I have the same questions as yourself regarding why the 2.0 got better specs.
@ignacmc once Ive installed a pulley flush to the stepper motor.
After I’ve tensioned the belts with 25N and started up I heard a grinding noise. The deflection was not noticeable with bare eyes but there was definitely one, and the pulley started grind against the motor.
So from my experience displacement occurs also with light loads .
Setup is the same as yours on the Anycubic predator.
The stepper motor in question was a moons ms17ha2p4200
@ignacmc i think what he suggests when the belts displace the motor shaft, this bearing would prevent or alleviate the displacement of the motor shaft and thus reduce strain on the motor bearings . The strongest force would be on the lower side of this flat bearing.
I liked this idea and never thought of it before, I’ll look into that.
I’m planning to make an automatic belt tensioner and a more sturdy motor shaft would help a lot.
@bberger I have a predator with a flying orbiter and remote cooling, linear rails, Kevlar belts, with moons p4200 0.9° and duet2.
I’ve bought them without knowing anything about back emf or knowing about the stepper calculator tool.
They are about 1.5 years in use.
I was trying to fight VFA’s and while they got slightly better they are still there.
So my reliable travel speeds are max 350mm/s if I go higher I risk layer shifts if the nozzle bumps slightly in to the print. Still fighting with ringing if I go higher then 600mm/s on jerk.
@lo-fi my vpn endpoint is my synology NAS maybe that’s why it just works 
@lo-fi my printer has a static up assigned.
I just connect to my vpn and put the local ip of my printer in the browser no additional configurations necessary.
@0__felky__0 ofc, it works well via vpn and it is reasonable secure this way.
@eranglr I’m using node red with a telegram_bot node.
You can relay the telegram chat to ssh -> duet.
That way the telegram chat would just like a ssh client.
I use it just to push notifications on errors or when a print is completed with snapshot of the print.
@jay_s_uk thanks that’s great news, looking forward to mess with the code.
@ignacmc I’m using a Super Pinda on an Anycubic predator. I use it solely for z datum.
When I’m calibrating I’m using a fsr nozzle probe. It works great that way.
Due to the offset and effector tilt I would strongly advise against using it as the only z probe.
@obezruki i can imagine two possibilities
1.Check your line width and flow in Cura, I had once problems printing TPU not realizing I had the line width set on to 0.04mm. Yours could be set too high.
@heartleander81 that’s great
I’ll make myself a pcb described on the same page for my duet2 when I have some spare time.
@heartleander81 I think a duet 3 has a 5v PWM output. Check this link out https://duet3d.dozuki.com/Wiki/Laser_PWM_control
@heartleander81 I’d like to share my experiences with a similar blower fan DC9250.
I connected it to the fan output of a duet2 and pulled the voltage of the PWM input of the driver up.
I tried different resistor values 1k -50k but I had problems when I turned on the bed heater the RPM of the blower would rise too.
I’ve opted for an optocoupler which eliminates the changes in rpm but my setup doesn’t control the rpm of the blower linearly and it depends heavily on the Frequency settings.
I didn’t bother to investigate it further since it works reliably enough for over a year.
I think a real PWM output with high 5v and low GND would work better.
If you come up with a better way please share.
When a SSR or a mosfet fails they often keep the output on and heating up uncontrollably.
I’m considering using 2-3 relays just for safety reasons.
The normal coiled ones are enough if you use them just for turning the power off. They would switch on when the printer goes on and off when there is a failure or the printer goes off.
The only caveat is that I’m using a WiFi power socket so I can turn off the whole printer over Wi-Fi and NodeRED and I would not need any additional wiring.
I’m having the same issue with my predator and a magnetic PEI sheet. Also insulated and with an enclosure.
I’m re tuning my most common Temp ranges 58,70,85,110.
I had some partial success(with completing a tuning process) , if I start my Bed PID tune already warmed up from a previous tuning process.
Since I know that you have also a predator, do you care to share the result of your resonance analysis?
Sadly I have more resonant frequencies and the input shaper isn’t helping much in my case. The most prominent frequency is around 41.5 hz and it looks like the zvd is my best option.
I was Even wondering if installing steppermotor
Dampeners would improve my situation.
@dc42 thank you exactly what I needed. I am going to test right away.

I've tested it and it seems to work. Thanks again.
