[Issue#166] How to energize motors? About GRBL HAL

Issue #166 | 状态: 已关闭 | 作者: tomauga | 创建时间: 2017-06-09

标签: TinyG

I need to be able to run multiple files on the same work piece at the same coordinates and change tools between. (Using F-Engrave)

I haven’t found a way to energize/lock motors so this can be done without accidentally changing an axis. Is there UI for this?

I haven’t tried tool changes in a gcode file yet. Is this supported? If so are motors locked? How to resume etc.

I do this all the time where I have one path for a large tool, and a second for the vbit.
I load the first file, Home, position the bit, and hit play. When it is done, I home, switch the tool, position the bit, and play the second file.

When the first file is done the bit returns to what looks like work X0, Y0 and with Z elevated, but the display doesn’t show X0, Y0 so I haven’t trusted it which I why I re-home, and then position the bit with my 3 Axis block.

Thanks Patrick. How are you setting the home position? And which controller are you using?

In ChiliPeppr there is a button to energize the motors so you dont accidentally change the x/y.

I’m using the grbl controller and I have a known size aluminum block. http://triquetra-cnc.com/product/triquetra-p3-auto-zero-touch-plate-with-g-code-generator-copy/ <http://triquetra-cnc.com/product/triquetra-p3-auto-zero-touch-plate-with-g-code-generator-copy/>
Can’t say enough about Charlie and his stuff.
It came with a macro that lets you probe all 3 axis and then I have another macro that returns to X0,Y0,Z0 so I can verify the bit before I hit play.

When my machine is sitting there the motors have enough holding strength to let me change the bit.

Which grbl controller are you using?

#5 – dirtdiver9 于 2017-06-09

The older X-carve one. Daughter card to the Arduino.

I leave my steppers enabled all the time when connected using grbl. That said, if I change tools, I think it’s good practice to home the machine afterwards. Are all of your cuts starting at 0,0 or do you have them already arranged in your workspace?

#7 – tomauga 于 2017-06-09

My cuts all start at 0,0. I was just hoping Cheton could add a button that would energize the steppers. I can always use the $md/$me commands for TinyG. Just not very friendly.

Another problem (which I reported) is not all the software brings the spindle back to 0,0 when the file is finished and cncjs hasnt been working for me to set workspace 0,0.

#8 – cheton 于 2017-06-10

Sure! I will add Motor Enable ($me) and Motor Disable ($md) buttons in the next release.

#9 – rgallus 于 2017-06-13

Thanks cheton, I was going to make this same request.

@tomauga @rgallus

May I confirm if you’re able to use {me:0} and {md:0} commands from your side as well as sending $me and $md commands? I’d like to send commands in JSON format, just want to make sure if can work for TinyG firmware v0.97.

#11 – rgallus 于 2017-06-18

Thank you for your response. I had forgotten about the $md and $me
commands. I reviewed the TinyG information and found them. I very much
like cncjs and want to thank you for its development. Looking forward to
the next update.

@cheton Yes, I have access to both json and $ versions of the command. Please note that they are only active for the timeout period. ChiliPeppr gets around this by continually sending me until you press the un-energize button at which point he sends md.

#13 – cheton 于 2017-06-20

@tomauga
Thank you for reminding me. I will follow the same way for energizing motors:
https://github.com/chilipeppr/widget-tinyg/blob/master/widget.js#L674

#14 – rgallus 于 2017-06-20

I only have the ability to use $. For some reason I can’t energize Jason.

@rgallus
Could you type $sys command to show your settings? You can try setting {ej:1}to enforce JSON mode.

#16 – rgallus 于 2017-06-20

Both systems now work. Did not know about using the bracket when writing
from the console.

Thank you

Rick

Added in the commit a48de34fb178e17e4f9747974862c2de1ab23459. You can see a preview below. I will publish a new release in the next few days if no issues found.

Looks good. Can’t wait to try it.

Thanks,
