I have the XL Hotwire CNC from Hotwire Foam Factory, I have a new controller (Jackpot by V1 Engineering) running FluidNC that I will be using. I know that there are a couple of things that I will need to do to get this up an running, but I am wondering if I can run my hotwire using Gsender. The current GCode I am Producing only has X and Y, it is 4 axis capable but this is using 2 individual tower arms. To not get to much in the weeds for now I would just like to get the 2 Axis mode working.
Is there a way I can set the software up to only run those without the Z? I know the laser feature exists but I’m wondering if there will be an issue with trying to run it like this.
As I progress I will keep this updated.

@captainpda Welcome to the group. Christian.
To start, you should search on fluidnc and gsender. There are a few threads on using gSender with controllers running fluidnc. In short, it is not fully supported, but it can work.
As far are no Z moves, if there are no Z commands in the gcode, gSender will not by trying to move the Z axis. I run laser gcode in gSender frequently. It does not cause any issue since there are no Z moves in the gcode.

That’s awesome to hear, Thank you so much! I am currently in the process of connecting the MX4660 4 Axis Stepper Driver to a control board. I currently have 3 options of BTT SKR-PRO-V1.2, V1 Engineering Jackpot Board as I said above and an Arduino Mega 2560. If my goal is to us Gsender, should I use one of those other boards as a controller and put GRBL/GRBLHAL on it? This is just general thoughts while I have everything open and nothing finalized.

@captainpda You are way beyond my competence level. 😀 I’m sure that others here will be able to contribute. If you need anything more, open a support ticket with Sienci. I’m sure that they will be able to advise you.

From my experience, if you are looking to put in a new controller/Grbl take the opportunity to step up to GrblHAL as it is a) newer and better supported, and b) multi-axis natively for when you are ready for that step. I don’t know if there is a GrblHAL port on Atmel 2560, I opted for a Teensy 4.1 processor module in a Phil Barrett break-out-board as this gave a much better IO support (with opto-isolated IO, relay control pins, and external stepper driver sockets).
My project was up-rating an older ShapeOKO CNC, not a hot-wire machine, and I have XYYZA axes, but the concepts are broadly similar.
I can’t comment on not using Z, other than watching for calibration/homing to ensure Z is excluded so the machine doesn’t fail to get homing signals. This is a config issue, not a full GrblHAL rebuild to my knowledge and understanding (such config as can be done through gSender)
