Ultimate Guide: Sienci Labs SuperLongBoard Modbus Control

* See pinned comment for a minor update related to the SLB profile which isn't used anymore. *
Are you frustrated with the inaccurate RPM control with a digital converter and PWM coming from your SuperLongBoard CNC controller from Sienci Labs? Then this video is the ultimate solution.
In this video we'll show you how to reprogram your PwnCNC VFD to communicate over Modbus with your SuperLongBoard controller for the most accurate control over the RPMs your spindle motor runs at.

Great video, amazing that you're offering free cable exchanges. One clarification is in the gSender Firmware tool the "SLB" profile isn't used anymore since once you're connected with "grblHAL" as the firmware on the connection dropdown, you can just have any "LongMill" or "AltMill" Profile selected in the Firmware tool profile dropdown and it'll show you all the right settings. Also when you set the remaining settings remember to turn the SLB off and back on again to make sure they take effect. Pro tip: in gSender's console, if you press the 'Up' arrow on your keyboard, it'll bring up past commands that you've sent so you don't need to retype them :D

Thank you for the additional details. I've pinned your comment to the top so others will find it and I've updated the description to make note of these differences since it's impossible for me to re-edit/replace this video.

This is great, Daniel, I definitely want this cable!! 😃 I absolutely love how you're always working to improve things and make owning your spindle better for us users. Keep up the great work. 👍👍

Right on! Can’t wait for a new cable.

Thank you so much! Video was dead on got my cable already swapped out and followed the process and it is working perfectly. Cable is on the way back to you! Amazing service, support, and innovative products for sure.

Got my cable in and replaced this weekend. Works great! Previously my RPM was 10%+/- what gSender showed and now it's at most 10RPM +/- Nice job getting it worked out. I'm fine connecting inside the controller with the phoenix connector but if you wanted to go with the crimped on rj11?

I have a long Mill and now a SLB, I also have one of your 2.2k water-cooled kits. How do I get a cable?
