I have both of these but have not installed yet. I am trying to understand how they work, in software. - What GCode tells the machine that a new tool is needed (T + M06??)? - In response to that - without an ATC - the machine pauses and waits for me to change the endmill? - and when I “continue” it navigates to the toolsetter, touches off - does the Redline controller have a popup? Or is it the same UI as resuming a manual pause? - with an ATC - the machine pauses GCode execution and moved to the ATC position and switches endmills - navigates to the toolsetter? Or is the Z offset for the tool already known - because it was previously setup? - returns/moves the where the GCode left off - continues executing GCode I want to better understand how it all is going to work before I physically install these components. Also, since I use Blender and FabexCNC (AKA BlenderCAM), I need to know that it will generate the proper GCode. One concern I have is, with my old Onefinity (Buildbotics), I used an M00 to remind me to turn on the spindle and dust collection. That M00 doesn’t work with my Redline controller. I’m worried about other incompatibilities. ---

I have Elite Gen1 with Redline and Toolsetter and it works similarly as you described: - It sees the toolchange command in GCode, it shows a popup that toolchange is needed, and the spindle will rapidly move to the predefined toolchange position. You’ve to confirm it. - After hitting OK it moves to tool change position, and after you change the tool you need to confirm - After confirmation it moves to toolsetter position and touches the toolsetter - Resumes the job ---

As far as the M0 code goes the Redline controller does not support a M0 command yet. The supported G codes are found here at the Redline website. > **[G-Codes - Supported Codes - RealTime CNC Documenation Hub](https://docs.realtimecnc.com/gcodes/#g-codes)** Also you can find the redline controller manual at the onefinity main website under support - resources/manuals Cheers Joe ---

I think that may be enough info to give me the confidence to take the next steps to install the ATC and Toolsetter. Thanks for the help. ---

Does the tool get uninstalled from the spindle on power off? Does the controller assume the spindle has no tool installed upon power on? Does it prompt the user to confirm this? If the spindle has a tool installed, does the controller ask the user which tool is installed into the spindle? If I have tool 1 installed, and I put the GCode “T2 M06”, it needs to put tool 1 back into the ATC. AND it needs to know which slot to place it. So it MUST know which tool is installed. I’m not clear on how the controller knows this at startup? Does it retain this information across power off/on? I’m probably going to have to test these things, and have my hand over the kill switch. I am convinced that it is going to try to uninstall a bit at a slot that is not empty. ---

The Redline settings has an option to treat an M6 as manual tool change. It is supposed to move the spindle to the configured location, and allow me to manually change the endmill. It requires the toolsetter to be configured. I have done this; but when I run the GCode is stops at the line with the M6. Also, it appear the controller is stuck on that line - even though the UI shows it reset to line 1. If I try to run again, it warns if I can to continue from line 5 (the line with my M6). I reset and try to run again, it gives me the same warning - saying that I’m still on line 5. I have tried variations: M6 M06 T1 M6 T1 M06 M05 T1 M06 All yield the same result. Does anyone have this working? ---

What version of code are you running on your Redline Controller? I had this working before I upgraded to 1.3.10 with the Fusion 360 post processor. After the upgrade I have the same behavior you are seeing. Once it gets to the M6 in the gcode it just hangs. For reference here is the gcode from the Fusion360 post processor: T1M6 This worked fine before the 1.3.10 upgrade. I opened a case yesterday with Onefinity and they punted to Redline support. I haven’t heard anything back from them. If I hear back I’ll post what I find out. ---

I’m using FabexCNC (formerly BlenderCAM). I expect to have to hand edit, or tell FabexCNC to prepend GCode that I specify. I’m just trying to figure out what that GCode is. Above is me trying various things - based on my understanding of what the GCodes mean. Oh, and I don’t know what PP means. ---

It may be a good next step to share an example of the gcode your post processor produces - perhaps model a small square and have a 2D contour toolpath of its perimeter with two different tools. The resulting code can be examined to see if there is anything there that the Redline controller doesn’t like/can’t understand, or more specifically is causing the tool change issue you described. ---

I heard back from Redline support yesterday. It used to work with the command to set the tool (T31 - change to tool 31) and the M6 command on the same line with no spaces like this ```auto T31M6 ``` That’s how the current Redline Fusion360 Post Processor handles the gcode. In 1.3.10 both commands need to be on separate lines like this: ```auto T31 M6 ``` I went and edited the gcode output from one of my tool paths to reflect the separate lines, here is an example: ```auto (2D POCKET1) T31 <-----Command to set tool M6 <-----Command to initiate tool change S18000M3 G17G90 G54 G0X12.4403Y6.2634 ``` Once the TXX and M6 commands were on separate lines everything worked as expected. Not sure if they are going to fix it in firmware or just update all the Post Processors, but if you are running into this issue editing the gcode to separate the commands on two lines is a workaround until they get it sorted. ---

Thanks. I’ll give that a try. It’s unfortunate, because I don’t know if I can tell FabexCNC to add a two line header. I think it may be only one line. I doubt I can encode a newline either (with \n or something). But, I pretty much always view the GCode before copying it to my thumb drive. And historically, with my BB, I always manually added an M0 (reminding myself to turn on dust extraction). So, it’s annoying, but I can hand edit and manually add the newline character. I’ll try that today. ---

Well, that worked. You see above, I tried a bunch of variations; but the one variation I hadn’t tried: T1 M6 on separate lines. I got to see the tool setter flow for the first time. Even without the ATC, this is a step forward. I think I probably need to fully understand how this system works without the ATC first. Thanks for the help. ---
