don’t know what a ‘Uno setup suite’ is, so I doubt I used one 🙂
I was referring to your initial How-To, post
Was I incorrect in assuming that your Arduino reference was an Arduino Uno?
So once paired, Coolterm on your PC can send the “AT+UART=230400,0,0” over the BT link to the far end HC-05. Cool.
Progress!
What type of machine do you have? Belt, Screw, ?
When I see 35.9560 mm/rev, I assume XL belt machine.
My Shapeoko with ACME Z moves 2.1170 mm/rev, I am just curious what you might have. I have NEMA17s
Here is a link to a configuration set for my machineIf your 1.25mm/rev is correct, your setup should have A LOT of extra torque available with a NEMA23 driving it, as you are moving only about 60% per rev when compared to mine.
Do you perhaps have an alignment issue with your z axis?
Or binding at some point(s) along travel?
Really heavy spindle(assuming it is a spindle, or glue or laser)?Be aware that your motor assignment Y1,Y2,Z,X is different than mine, which is X,Y1,Z,Y2. Not an issue, just different.
I assume you can see why I prefer to communicate via dropbox (or equivalent) for configs, G code, etc.
If you plan on communicating with the form a lot, you should try one of these free cloud services.
As an alternative, you can place your configs between code tags on the forum, still harder to review due to fixed window width.
It would look something like this[fb] firmware build 435.10 [fv] firmware version 0.97 [hp] hardware platform 1.00 [hv] hardware version 8.00 [id] TinyG ID 2U2971-YTVI just reread
I just had a thought. Could I redefine the drivers in tgfx & double up the Y driver? ie. turn it into a 3 driver board instead of a 4, then use an external driver to handle the extra load?
If the controller output is the issue (i.e. the signals driving the driver are bad) then you could, as you suggest, reconfigure tinyG as a three axis and drive two motors with three possibilities:
1. Wire two motors to the onboard driver. (this is my gShield comment)
2. Use one external ‘Polulu’ driver to drive two motors (your suggestion)
3. Use two external drivers wired to the pin headed, the controller should easily handle two external driver loads.In all three cases you have to wire one motor to move the opposite of the other.
As a generic comment, IF the controller outputs (port pins) have failed for some reason, I would expect more to fail in the near future, so you could end up replacing the tinyG anyway. A uC failure would suggest that either bad voltages made it to the uC device or some sort of device defect; both of those conditions tend to migrate around the device over time.
When you have some time, give this thread a read
The wireless alternative…..
