Nah, didnât work. Iâve spent too much time on this issue already. Itâs perplexing why I cannot get analog or RS485 working on the SLB so back to using my keyboard and potentiometer on the VFD. I may at some point try to install my Delixi VFD to see if I can get it working (the same VFD that PWNCNC uses). The SLB PWM for my 20W laser doesnât function either. Itâs either off or on full power, so I manually regulate the voltage to get by. Thus far, I do not see any advantages of the SLB except it runs faster which is something I guess. Will be attempting to hook up the A Axis next week. Hopefully, that will not prove to be as frustrating. Are you using a VFD/Spindle? If so, would you mind sharing some pictures of your wiring?
Hi @CraigCoulter, did you see that Johann on our team completed the document for H100 wiring and hookup? You can find it here:

The documentation looks really good. The content also translates to my Huanyang v1 VFD - with setting correct PD settings. With all the âRESTART <insert SLB/VFD as appropriate> BY POWER CYCLINGâ (in all caps no less) steps, I think my âturn it off, go to the house, and have a beer about itâ is what finally got it all working for me.

Have a new altmill i just finished assembling , can get all the motion from each axis but cannot get the spindle to fire up , even tried reloading gsender several times . The instruction pics in the guide are different from what i get in g sender menu in the latest version . The instructions dont seem to match
I think the âRESTART <insert SLB/VFD as appropriate> BY POWER CYCLINGâ steps in both the AltMill Spindle Kit Setup (https://resources.sienci.com/view/am-spindle-kit-setup/)and Unofficial Guide (Linked Above)are crucial.

I have tried that half a dozen times , even removing g sender and reloading it. idont get the same screen for the 395 to enable the H100 and says nothing about the spindle .
this is what i get in my gsender
Thanks
I suggest you open a support ticket with Sienci.

well took it to where i work and my boss sets up drives quite often and we went through this one ,
followed the unofficial guide for settings found on here . He also noted the drive was set for 3 phase 380 volt and peramiters
were not inline for the spindle . We left it control on the drive for now , until we figure out the gsender issue , spindle works awesome and super smooth and quite compaired to the router of my old machine . He figures the drive is on the edge of being to small for the spindle at full rpm , so we dialed it back to 80% and works perfect , just the spoil board left to go before test carving.

@Walter when you make your initial connection to your machine, you need to make sure you select the right firmware in the dropdown. Make sure you click âgrblHALâ and not âgrblâ. Thatâs the problem youâre having
Itâs been a while since Iâve worked on this due to work and life but I wanted to see if the Huanyang HY02D223B was compatible with the new instructions and if there are any limitations I need to consider.
Itâs a 2 phase 2.2kw VFD but I couldnât find how it relates to h100.
Iâm in the middle of connecting my new spindle cable so donât mind the U V W
@cncdm your VFD is an HY-type, so hopefully you should be able to follow this guide instead and get everything working:

Iâve got a GS20 VFD that Iâll be using for my Altmill when it comes in. My VFD has a RJ45 jack.. of course. I also have a RJ45 in my enclosure that I was using on my previous CNC to send PWM, FWD, REV, DCM and also carried an estop output for Masso controller.
Couple of questions:
1⊠What is the pin out on the RJ11 on the SLB? My current plan will be to use the RJ45 with an adapter to RJ11 to connect to SLB and drop the estop I suppose.
2⊠Is the SGND tied to ground on the SLB side? Currently, there is no continuity between ground and SGND on my VFD. My assumption is that SGND should only be terminated on one side to prevent a ground loop. Or does the SGND even matter in this case given distance of cabling is quite short but it is within a few inches of spindle drive cable on my enclosure.
Thoughts and tips are appreciated, just trying to get prepared for the upcoming arrival⊠well guessing at least 12 weeks still but would like to hit the ground running.
I am also assuming that the GS20 config in gsender is RS485 not PWM as GS20 is 0-10v only, no 0-5v capability. Honestly, I find the 0-5v convention a bit odd for spindle control as 0-10v seems to be the more standard setup.
Sounds good Mike 
Iâm not familiar with the GS20 VFD so itâs good that youâre scrubbing up on this stuff now while you wait for machine delivery. To your questions:
- The pin out on the RJ11 you can find here Technical Manual - SuperLongBoard
- Be aware that the GS20 profile isnât currently supported in our firmware so you wonât get 1-click setup for it. All this means is that youâll need to read your VFD manual to find the registers for Run/Stop, Set Frequency, Get Frequency, and the commands for Run CW, Run CCW, Stop, and then after that might just need to tweak the input and output multipliers/dividers once you receive and set up your machine. In the future we might be able to expand to support the GS20 if others are using it too.
- Regarding adapting the existing hookup you use, that may still be able to as well. Many VFDs have a setting to change requiring a 0-10V signal into 0-5V (on the H100 this setting is F070 I believe) so if the GS20 has this option you could try doing this instead. Honestly the reason we stuck with 0-5V was because many VFDs can do this, and those that canât support RS485, plus we wanted to maintain backwards compatibility to other hobby CNCs and accessories that were build around using 5V
- For RS485 hookup, you shouldnât need SGND I believe, especially on shorter lengths. If you hookup with 0-5V, then youâd want to use the SGND on the SLB
Hopefully that answers most of your questions!
