I Can't get the machine to do the speed I'm writing in the INI file

Hello all!

I've been encountering a problem for a while now on linuxcnc. My project is a Linear Delta Robot used for milling. 
My problem is, when I run the configuration file on any G-Code, the speed of the motors is slow no matter what the speed I'm putting in the INI is.
And also, when I'm setting the StepConf file, in the test-axis section on each axis the motors seem to be working perfectly in terms of speed. But when I run any G-code on the same configuration file, the speed gets reduced so much. 
Another problem is an error I get quite often, which is, joint 0 has a following error. I wish someone can guide me through this error.

And thank you.

What is the feed rate set in gcode?
Does the feed rate change when moving the feed slider in LinuxCNC?

I think thus sounds like the step-rate required to get the desired speed is higher than the system can generate.

What is your SCALE, MAX_VELOCITY and BASE_PERIOD?
