I have a 2x32 Dimension Engineering motor controller (actually have six 2x60's, two 2x25's, two 2x10's). I have used them to control wheelchair motors for robotic projects. I love the EZ-B application when using the servo app (mobile) joystick which is VERY smooth. However, when controlling the 2x32 using RC mode, it responds great, but when the Joystick is "autoreset" (center), the motor still runs, but very slow. Looks like the lowest position was sent to the controller, but not 90 degree (stop motor). I had to add a "STOP" button and script SERVO(D0,90),SERVO(D1,90) to stop the motor. I like the servo control but am thinking I should use the Serial protocol to control the 2x32. Anyone had success with either protocol and the servo joystick? thanks! Doyle
What control in ARC control are you using for the sabertooth in rc mode?
Because it doesn't sound like you are using the concept of a movement panel. Click on the words Movement Panel that are in blue, as that means links.
Virtually everyone here uses serial mode and either the Sabertooth Movement Panel or the custom Movement Panel using serial commands depending on how the motors are being used. I don't know of anyone doing R/C mode.
Also, there's lots of activities that will teach you how ARC works. Check it the word activities by clicking on it.
To find more, use the learn section. You can click on that word as well.
RC mode is the best because it includes speed control, specifically when using the mobile joystick control or a real joystick device. This is because rc mode would use the continuous rotation servo movement panel.
DJ, if you set speed ramping with Dimension Describe software the serial mode works perfectly with the Sabertooth Movement Panel and a joystick too (funny, teaching you about software you wrote). R/C mode has had reliability problems in the past when users have tried it.

Really? Wow that's awesome. Did I add speed control with serial mode in the sabertooth control? If so, I must be losing my mind because I forgot ha. Must be the jet lag. I've been in Shenzhen the last week. Days are upside down
Wow! Great response and advice here! I looked at the Movement Panel and used it, however, i like the servo joystick style widget to drive the bot, like a PS2 joystick. Is there a way to code the stick? I want to use the mobile app to drive. I have a STEM show in 2 weeks. Check us out! Www.kitsapcreate.org Thanks for the great advice! Keep 'em coming! Best, Doyle
Yes, use the movement panel. Click on it and read what a Movement Panel is.
