I received some of the first batch of G203's that Geckodrive is now
selling. I installed them in the same 3/4 axis case that I use for
my G201 and G210 step motor systems. The installation was quite
simple with the installation differences being that the New G203 use
a opto on the disable line which necessitates a minor change in the
wiring for my enable/disable switch, the common signal ground. and
the elimination of the 470 UP cap that was needed across terminals 1
and 2 of the Gecko drives.The footprint is the same and secures to
my heatsink the same as the G201/G210
I powered up the G203s with the case cover off of my control box.
The red light on the boards light comes on for a second then goes
out during the power on reset cyle. The Green Run light comes on
very quickly. A a noticeable thump sound from the steppers as the
winding engage. I test ran some 452 oz in stepper on my bench for
about 3 hours no load using a dos based program with smooth pulse
streams. No missed steps were noted using one of the torture program
that would tend to show step motor resonance issues. There were none.
One of the other nice things in adddition to all of the features
that there are in the G203 is that the motors were barely warn after
sitting in the reduced current mode for 1 hour.
I just finished running the g203 with mach3 with the pulse width
and dir set to 0 usec. No lost steps. The steps per unit was set at
20,000 and the velocity set to as fast as my pc could produce steps
with the kernel speed at 45Khz and about 135IPM. I ran the
Roadrunner.tap program faster than I could with the G201's as a
matter of fact it was AWESOME!!!
I plan to set it it up on my shop milldrill retrofitted with
ballscrews this evening and to run that machine with some 452 oz in
motor and then switch out to some 762 oz in motors then tomroow run
some of my 1303 oz in motors to see how the G203's run on a working
machine.
I am so happy with the results of the first tests that I am already
planning to come out with G203 kits and assembled and tested stepper
systems using the G203.
