So I have been playing with these servo motors for the past week or so and I think that I am on the right "path"

So far here is how I have set them up:
Duet2 Wifi + Breakout board

ClearPath Connector	Duet2 Break out board
Step+ (B+)	5V+ (from Heater6 3pin conn.)
Step- (B-)	Step- (from Drive5 conn.)
Dir+ (A+)	5V+ (from Heater6 3pin conn.)
Dir- (A-)	Dir- (from Drive5 conn.)
En+ (Enable+)	5V+ (from Heater6 3pin conn.)
En- (Enable-)	Ena- (from Drive5 conn.)

I have set the M569 parameters with the followings:

M569 P5 R0 T2:2:2:2 S0

Movements were a bit rough at first but after tuning the servos on the printer One motor at the time with the other one enabled and lock improved things by a lot.

I had drift in the coordinates at first, but I decreased the step/mm from the duet and compensated on the servo config, then played with the M569 timing values a bit. I think they work good now.

Will keep you posted when I have print results.

Ok small update: (A positive one)

I have unplugged all components from the board including Duex5 except power source. The board powered and the esp connected to wifi! wooohooo! I then reconnected all components one after another (Duet powered off during each plugging of course) and I was able to reconnect all components until full functionality again.

I am suspecting some cabling malfunction at this point, that would be the only logical reason I see. The printer works again.

Will keep you posted of further development.

Thank you for your help

Good day all!
I know the topic has been touched a few times here but I cannot find the answer to this question.

Q: Can I map 2 additional Axis for the build plate to tilt around the roll and pitch attitude using three Z motors
My bed design can give me around 30 degree of freedom (+-15deg) in all direction.

I have no knowledge about delta printers, but I would assume that they share some similarities with what I am trying to achieve.

I am also totally aware of the immense slicer challenge I am facing. But one bite at the time is how you eat an elephant.

@Veti I am using the one provided with the Duet in the first place. are you saying it might not work?

Device manager does not see it... I'll take them out tomorrow for close inspection of the boards.

I searched the forums for similar issues but could not find anything.

It started to loose wifi connection every 10 seconds, then nothing....

I have checked all wires, made sure no dust was on the board and on the Duex5.
Only a solid red and solid blue leds are on when plugged in, no flashing. The Duex5 shows no led at all.

I have tried un powering the Duet and connecting usb cable. YAT sees nothing either.
All fuses seem to be good.

Is there anything else I can try? Board has been on this machine for 2 years.

Thank you for your help.

Yet another jerk and speed topic....
Anyhow, as I was performing some flow testing last night I came to a halt when I could not raise speed higher than 350mm/s on a 200mm single wall cylinder in vase mode.

Observations

• My settings were:

Duet2 Wifi + Duex5
RRF2.05.1

Accel:
X - 20,000
Y - 20,000
E - 3000
Z - 200

Jerk: 
X - 700
Y - 700
E - 1000
Z - 50

Starting from 300mm/s and up I could see that some section of the perimeter were being performed at different speed and some vibration was occurring.
The DWC speed indicators were also witnessing that speed variation.
I then tried to raise speed again, but nothing would happened, it was in a lock.

Surface finish was like if the tiny segments from the GCode were amplified.

• Here are my resolution settings from Cura (I know 0.1mm resolution might be aggressive):
  

I then tried something....
I bumped jerk all the way to:

Jerk:
X - 3000
Y - 3000 

Magic! speed went up well passed 500mm/s and surface finish was back to normal~ish.

Assumption
Since the GCode little segments are requiring direction change that are so small, the acceleration settings are not used, but jerk is instead.

Question
Is there a way to maintain speed on curves without having to bump jerk? Anything higher than 650-700 triggers step skipping at those accel and speed value.
And the 20000 accel is what allows me to print fast without skipping. Not that fast, but the max I can go with this issue for now: https://youtu.be/ZZDuX6hcd28?t=294

@BDubs Thank you very much for this advice.

@alankilian thank you very much! the more resources the better! I am keeping that in mind

@alankilian said in ClearPath Servo Motors Testing - So far so good:

@Mirage A colleague of mine from when I lived in Minnesota has made sand plotters for decades and after a successful (Like $2 million on a $50,000 goal) Kickstarter he sells them now.

wow ! i did not know these existed until I saw @mrehorstdmd 's post! Beautiful, wonder if this would calmdown my kids....

@mrehorstdmd This sand table is amazing! totally mesmerizing!
Thank you for your feedback. I am going through you impressive material.

Hopefully the auto tuning capability of the clear path will give me the right tools to achieve descent print quality.

Looking good, can't wait to see a print

Same here! been working at this since July. Getting closer. I have yet to see one successful print created by these motors. A few people have tried, but I have not seen a single confirmation of success.

I have to admit that I am a bit nervous at running into the same dead end... But! luckily I am quite hard headed
