Re: Commanded velocity seems to be fluctuating

I agree. I did that when I first put it in, but it works just fine when I take it out. Changing the acceleration on that axis fixed the problem. Really appreciate the help!!

Re: Commanded velocity seems to be fluctuating

Nope, it is actually an auxillary motion, so not even used while printing is happening. I will turn it up and give it a shot. Thanks for the help. If this solves it, I know I would never have figured that out on my own.

Re: Commanded velocity seems to be fluctuating

Interesting. If I wanted to use a high acceleration, are there ways of going about tuning the look ahead to deal with that? Acceleration is one of the things I want out of this platform. #include "KMotionDef.h" // A KMotionCNC MCode can be configured to set the temperature setpoints // using P and Q...

Commanded velocity seems to be fluctuating

Hi Tom, I have constructed a 3D printer using the Kflop and Knozz boards. I am testing it at the moment, but I seem to be having a problem with the commanded velocity fluctuating on long paths. Also, the velocity never seems to get to the actual target velocity. I have a video (don't know how to att...

Re: CoreXY Kinematics

Hello Tom, Actually, it turned out to be a silly mistake. I didn't realize that you had to take the newly compiled .dll files from the Debug folder and copy them into the Release folder. After I did that it works like it should for the most part. When I stop hitting the jog button there is a short p...

CoreXY Kinematics

I am building a 3D printer using the CoreXY movement scheme. I used the Kinematics3Rod file as a template to write a new kinematics file, but when I use these kinematics it does not behave as I expect it to. When I jog any axis, I get movement in all axes. Can you tell me what I am doing wrong? I su...
