Gecko 214 Wiring Diagram To Acorn

Hello, does anyone have a wiring diagram or photos of the correct wiring? I have read a few threads and am more confused than anything. I have been getting "roughness" in the operation as well as rotations of the motors on power up.

There are many more connections on the G214 that are not shown on the 201 drawings that have been Posted.

follow the 201 schematic.
https://www.centroidcnc.com/dealersuppo ... 977.r4.pdf

and most are overlooking this......when open loop stepper motors it is imperative that the motor,drive and power supply be matched/balanced and configured properly. Be sure to follow the guidance found here from GeckoDrive. https://www.geckodrive.com/support/step ... asics.html

please List your motor make model. Power supply rating and current limiting resistor value.

choose Gecko G201,G214 in the Wizard drive type menu and be sure to press "Load Drive"

I have selected the 201, 214 selection from the wizard. Followed the guidelines.
I am using a 48 volt Power supply.
Motors are as follows:
X - Rtelligent - #86AM120 4 AmPs
Y - JMC Motion #86J18156-845(k) 4 amPs
Z - OMC #34HS38-3008S 4.2 amPs

That is quite a hodge podge of stepper motors. Spec sheets for each one would provide the inductance rating.
Square root of the inductance rating * 32 would give you the optimal voltage.
You also have to take into consideration the type of windings each stepper has, whether they are 4, 6 or 8 wire and whether or not you wire in series or parallel if the latter. Parallel is usually best. There are different current ratings for series or parallel hook up.

For those using stepper based systems, Geckodrive provided a GREAT guideline on steppers, torque, power supply sizing and wiring. Everyone should read it and follow it:https://www.geckodrive.com/support/step ... asics.html

Just slapping stepper motors on a machine and arbitrarily choosing a power supply is not good practice. Performance is likely to suffer.

Getting parts during the pandemic has been a challenge. The motors were all the same as the y axis, but when two failed and no replacements for 6 months, optimal outcome went out the window. so your last comment was a bit harsh.

what value is the resistor being used for current selection on the G214 drives? (if you are over driving current to the motor it will be rough when jogging/moving it this is why i ask )

According to the documentation you do not need to use a resistor if you set the amperage using the dip switches.

I'm sorry, but you do need to match steppers to the machine, not only in size but also electrically. I have no idea if you know this or not. I have no idea if the motors are 4,6 or 8 wire or how you have them wired.

Many people arbitrarily buy stepper motors soley based on size and don't take into consideration the other pieces.

Are you in the US or where are you located?

If you can take the time to provide the information requested in this post, it will help us to provide you with better suggestions.

That includes the cut sheets on your stepper motors. Its not good etiquette to ask for help, provide model numbers and expect us to go searching for the documentation.

Have you resolved things or are you still stuck? All the motors behaving the same way?

I am still stuck. I currently have 1 214 working smoothly and I had to Put 2 - 201 back on the machine to get something done. I have 3 new 214 Rev3 just sitting because with 24 different setting combinations could not get them to run smoothly. I also have been back and forth with customer support with Geckodrive for the past 4 months.
I am located in Ontario, Canada in a small rural community.
