SLB gSender 1.4.9 grblHAL wont run Spindle and Error 1

SuperLongBoard ❓Question
1

My LM Mk2 48x30 (using gSender 1.4.9/grblHAL) via SLB is not running the spindle even though the CW (M3) and Stop (M5) are able to be activated. Also getting Error 1 Expected command letter G-code words consist of a letter and a value. Letter was not found.

I’m able to generate gcode from Aspire and run projects in gSender via SLB (manually controlling spindle on/off).

Longmill MK2 48x30 with the SLB running gSender 1.4.9 (Firmware SLB_B5.0.5).
Using Aspire 12.0.10 (Sep 9, 2024). Machine identified in Aspire is “Benchtop 48x30” Longmill; using grbl (inch) and grbl (mm) post processors.
VFD and Spindle: Huanyang HY02D223D Single and three-phase 220V 50Hz, 2.2 kW Power; 10 Amp Output; 2.2 kW Motor – Spindle is G-Penny BST2.2C 80mm 24000 RPM 220V 2.2 kW

Wiring between SLB and VFD: RS485 to RS+/- on VFD

Key settings in gSender: SLB_SPINDLE, enabled as spindle 0; Huanyang v1, enabled as spindle 1, SDV; Note: also tried H-100 as the default spindle with the MODBUS address as 2

This is a lot of great info, thanks for providing it @DLGai. Could you do another quick thing for me? Go to run the file like you’re trying to do, make sure the Error 1 pops up again, then cancel the job. Once you’ve done that go to Calibrate → Diagnostic PDF → and once you’ve generated it then post it in this thread. Once I have a look at that I’ll be able to say more confidently what issue you might be running into.

All the best, Chris

@DLGai would you have that info yet?

Hi Chris. Apologies for not updating things. I wasn’t able to isolate and replicate the error nor determine where the break in Comms was occurring. I ended up biting the bullet and got a VFD from PWNCNC. The Vortex upgrade to the closed stepper arrived a few days ago, just in time to coincide with the latest grblHAL version. All seems to be running great at this point.

Next week I will be running some test projects on the Vortex. I loaded the A axis post processor in Aspire and currently made the Vortex settings in grblHAL. Did some basic test moves to verify. I’ll peruse the forum but do you recommend using HAL or Edge for the closed stepper Vortex (with the SLB, LM MK2 48x30, VFD, spindle)?

Totally separate issue, was Windows 10 to Windows 11 forced updates wouldn’t fully install on the dedicated computer. My wife’s not happy I’m having to use my design computer in the shop. Timing sucks with lead time of your gControl so I’m looking at a refurbished Panasonic Toughbook for the dedicated.

Shame on not replicating it, but super chuffed to hear that you’re looking great on most fronts right now! Rough goings on Windows too - I always hate that sort of thing, and we’re hoping gControl helps with it

Regarding what to use for Vortex, I’d stick with the current main version of gSender using grblHAL if you want any sort of initial setup and reliability since the Edge release is the first one there’s bound to be plenty of bugs - but also if you’re willing to be generous with your time feel free to download Edge too, move away anything important to you, and let us know your feedback so that we can continue to make it better :smiley:

Guess otherwise I’ll close this thread then?

Thanks for the guidance. Yes, thread can be closed.

I mentioned to Andy and Jason at the Austin UGM that another issue I was seeing was the auto zero touch plate wasn’t being retained as the default in gSender. I haven’t tested the touch plate since I switched to the new VFD and since updating to 1.4.10. I’ll test it tomorrow and will start a new thread if it’s still happening.
