David
I'm back after the show and would like to get this up and running. I have a complete installation on the big Scara now.

All of the extruder speeds have been corrected but it essentially does the same thing. It homes perfectly at relatively high speeds without a problem. Then it starts to print and everything slows down, the distal arm just slowly comes in and crashes.
  links included the G-Code and a photo of the board installation.

The prox switch is worked exceptionally well so if anyone else needs a 5 volt switch I would recommend these. We need the prox switch on the proximal base in order to do continuous rotation.

David I'm using hybrid steppers so the voltage is not a problem because it has external power supply to the steppers. My minimum counts per Revolution is 800 selected on the hybrid steppers, I can't go any lower. So I don't use microstepping

The extruder High count might be misrepresented, I generated this file and that was left over from a print that I did on another platform. But I'll definitely check and make sure before the next test. Unfortunately I had to break it down because we have to go to a large show coming up in Pittsburgh. So I had to go back to my old platform.

I'm able to achieve relatively high speeds, so it's completely different when it starts to run the program , it as if the processor can handle it.
Like when I'm homing or moving into position to start the print

Did you get a chance to look at my settings, it's been awhile

David I was able to reduce the steps per/ degree down to 736. You were correct because after adjusting some parameters I was able to hold connection over WiFi and complete the Homing sequence. The scara moves at a good fast rate during the Homing sequence, but now the problem is as soon as the print starts it slows down to less than a snail's pace. No matter what speed I set in the g code it just barely moves , it's as if the processor is choking. What do you think

Micro stepping is set at 1 and the Homing speed is relatively slow.
M92 is 23563.7373. Steps / degree

My first problem is that I have 2 WiFi networks within range. They both show up as available but I would like to only connect to the new router I purchased which is in close proximity of the Duets. How do I get rid of the first router I entered? Because sometimes it can't make up its mind and it gets confusing.

I have strong WiFi signal - 36 DB (M122)with the new router I purchase purposely to be close to the unit. But even with that strong signal I get a (Ajax error, reason time out)
The Duets will connect up with no problem and the connection is fine until I start to enter commands. So if I ask it to print it doesn't get through the entire homing sequence and the connection is dropped. Then I get the Ajax error message.

It reconnects fine and stays connected but if I ask it to even home 1 axis it will disconnect???

No problem with testing, we just installed Duets on the large scara.

Prox switch

[[url]https://www.dropbox.com/s/pd58x96vdv9nci7/20180213_101118.jpg?dl=0]

I have a standard homing sequence for the prox, and after homing this switch is ignored.
And yes I have continuous slip ring .
What's the deadline to finish 1.21?

David I'm currently running smoothie with working continuous revolving future and in order for me to switch over this is necessary. I would appreciate if you could stick this into the firmware code.

David I don't think you understand my request.
I have a big scara , and I'm printing a large object with the machine in the center. Therefore I need to have the ability to go continuously in rotation as I built the object around the machine.

So what's the answer can we run 360 continuous?

I would like the ability to do 360 degree continuous prints. This means I'm printing continuously Non-Stop around the perimeter of the Scara.

Because of this request, I also have proximity sensor on the prox arm. This sensor requires 5v, so what's the best way to wire this?
thanks

I thought the group would like to know my experience setting up my Duet wifi board with my scara. I've previously had a smoothieware and decided to try the Duet and there is no comparison.
The Duet has fantastic GUI interface, and the help and setup files that David (dc42 ) has created is extremely helpful. Talking about David, he gives excellent support and helped me work through my small issues. If anyone was considering trying this board I would give it a super thumbs up.
I haven't had much time to fine tune the machine and it's going to be used for ceramics only.

Okay this command works (M581 TO Z1 S1 C1 ) and the switch when triggered stops the machine. However it stops the machine when it's first homing, so the print doesn't start. How can we delay this till after the first homing sequence?
