ModeratorHere is a recently successful thread
I have never done it myself, so good luck!
ModeratorA board from the early days then (before bootloader)
You in North America?
I am off to look for a recent thread where someone successfully flashed the bootloader.
ModeratorI would say R6 is all you need.
ModeratorThe CP jog Widget works similarly.
You could look at that code.
ModeratorFw=384.08 is, well, REALLY old.
Windows I presume.
Use this procedure to upgrade:By the way, don’t use tgFX, it is way past being retired.
Use CoolTerm or try ChilipepprModeratorThe schematic shows two nodes in addition to the switch.
Likely just above the push-button, but you’ll ahve to solder in some pins
ModeratorWhat you show is the CP start-up command sequence, which it uses to query tinyG for current state and status on initial connect.
I see no responses, sounds like you are sending but not receiving.Spin/Dir flashing thru all this?
ModeratorHaving never heard of a delta printer I did a quick search.
Is this what you have in mind?From a quick look it appears that there are 3 movement motors and a rotational motor. Presumably whatever software generates Gcode for the machine translates movement of the three legs into X,Y and Z equivalent commands.
So tinyG could probably handle that part.
However, again based on just quick observation, tinyG likely lacks the I/O and control capability for the filament feed, heater controls, etc.You might be able to do the job with a DUO+Ultimaker 5 motor shield running tinyG2, but that is just a wild guess
ModeratorRead this wiki item and its suggested follow-ons.
If you don’t have Xmax switch, then you can use Soft Limits.
Read that section carefullyModeratorA double fast (double speed) Spin/Dir flash LED indicates that a limit switch has been activated.
Do you have limit switches enabled?
Perhaps disable them and see if the behavior improves.However, it sounds like you have no communication with tinyG whatsoever, so you won’t be able to reset the parameters.
Moderatoravrdude -p x192a3 -c avr109 -b 115200 -P COM3 -U flash:w:tinyg-master-440.18.hex
Difference between your command and the one I reference is a “-e” option, which for reasons not well understood seems to be required in some (many, all?) upgrade instances.
Sorry, the post processor messages are very software package specific, can’t comment
ModeratorIf Spin/Dir is still flashing, bootloader is still running.
SPJS may have connected to the ftdi hardware (on tinyG) but tinyG is not running if the bootloader is.Make sure you exit CP and kill SPJS.
What upgrade procedure did you use?
You might want to try the procedure outlined here, if it is not what you used.ModeratorI assume you mean X heads into the Xmax rail?
Is $ex=2 (tinyG flow control = rtscts)?But even if it isn’t, not obvious why G00 X1 would over run anything.
How about G00 X1.0 , perhaps tinyG does not like whatever end of line terminator that gets sent.User Dave Hylands has developed a bunch of Python scripts, perhaps he will stop by and offer some suggestions
ModeratorOnly thing that looks strange in your parameter set are values of $xjm and $yjm, suggested values would be = 5000, rather than 100.
Give that a try
ModeratorNot with out a lot of programming effort on your part, I would say.
You could repurpose a limit input, but nothing in the standard release of fw connects an input to either freehold or cycle start.if you are a CP user, there may be a solution there for you.
