Just testing to see if any interest in a small hack for adding a Adafruit Trinket+Adafruit DRV7781 board. (Both small) and GCODE to the Nozzle Magazine. Right now, its prototyped and working but not yet on the nozzle magazine. Working stand alone on a metro M0 board (couldn’t find my Trinket M0 at the time) and a motor. Response seems pretty good. Motor stops soon as I trip the input pin.
I have a bit I’m playing with that implements these GCodes
M112, M112_estop // M112
M114, M114_reportPostion // M114
M115, M115_reportFirmware // M115
M119, M119_endStopState // M119
M220, M220_setFeedrate // M220 S<PERCENT> A<PERCENT> B<VALUE>
M804, M804_openNozzleholdder // M804 S<PERCENT> A<PERCENT> B<VALUE>
M805, M805_closeNozzleholdder // M805 S<PERCENT> A<PERCENT> B<VALUE>
If the S or A values <0 or >100 it shoots an error
Otherwise performs the action.
Each GCode is a blocking call. So must complete before next call is processed which makes M112 useless so have to fix that or drop M112
This is it doing the init sequence,
M115 to display the firmware version
M220 to set the Speed, Acceleration and Braking
M114 to check current position
M805 to make sure it’s closed
Any interest in this for anyone. If so, I’ll do more code work and post on github
Also, any changes. Is M804/M805 appropriate for example?

Ok, I have ordered them - will save me some work and I will be able to focus on my controller.
Do you have already OpenPnp setup (scripts ?) for controlling it ?

I am tempted as well. I have Peter's head, but I guess his nozzle holders are not compatible with the magazine ( they are spring/ball locked) - I would need yours.
How much is the shipping to EU ( Poland), I have not seen the price on your webpage ?

Hi all, our open-source Juki nozzle magazine design is now available on our website for those interested in getting one. It comes in two sizes - medium (10 nozzles) and large (20 nozzles). Mounts to 2020 extrusion and comes fully assembled with all mounting hardware. Made out of aluminum and stainless steel cover.
Limited initial stock available. For those who already pre-ordered, we'll start shipping it this week.
Here's a video showing how it looks/works like: https://www.youtube.com/watch?v=k5r8RprR_CU

It’s recorded on the iPhone but here you go. Its just my test setup not hooked up to openPnP yet
Once I have the another DRV7781 I’ll get it all hooked up with the trinket+drv7781 board and show it
Right now it’s a mess of wires from the metro M0 board but everything worked.
I did have to jump speed up to 1000 (M220 S1000 A0) otherwise it lacked torque so that’s something I”ll have to play with

Hi Jason,
Thanks
Quick Question as I can not yet find this in the wiki pages
In the GCode Driver Settings there’s 2 settings
Connect WaitTime
Command Timeout
Are those exposed as Variables I can pass them to my driver like F{FeedRate:%.0f} is
I’d like to pass T{CommandTimeout:%.0f}
My INIT string is M220 S1000 A0 B0 and I’d like something like
M220 S1000 A0 B0 T{CommandTimeout:%.0f}
I can of course just pass it with T5000 or what ever but if I can use the setting dialog I’d like to
