I am looking to retrofit the following, what Gecko drive will I need?
Also is there a good schematic of a controller board with Gecko drives
that someone can share?
My current Setup:
MAXPATH 42 Router (2x3 Ft) from MAXNC with original Controller box (Have had so many issues with this controller, basically no good! and poor support from original company)
Motors on Machine: Powermax II 1.8Deg /Step 2.3 A 65 Volt 71W Bipolar With Optical encoders mounted over the rear shaft of the motors.
Software: Upgrading to Mach 3 from original MAXNC (DOS/WINDOWS)
What I do: I do lots of 1/16 thick Fiberglas sheet pattern cutting and recently had been running the machine the whole day, until problem s with inacurate cuts stated surfacing. I have retuned the complete machine nechanically, but I am still having the same issues, when I say inaccurate cuts, I mean the machine taking a path of its own in some parts of the cutting program, I know it is not my programs because they run clean in another system, so things are pointing to the controller, this has in the past been the culprit of troubles and I am just too tired too deal with this controller anymore. So I need a good stable Control system.
Can you recommend:
1) Proper Gecko Drives for my existing motors, if you feel I could use better motors (with good speed and torque) please indicate which ones work best with Gecko Drives.
2) Company that sells, Power Supply, Cap, Rectifier, Cabling Size, Protection Fuses or Circuit Breaker, which Rating.
3) I want to drive the spindle and coolant via Mach 3, so I will need Solid state relays. I use a 2HP 30K RPM router.
4) I am not sure on the connection with the encoders, have done previous installations Step/Dir only with no encoders, simple 4 wire setups. Please indicate how I can do this with Geckos and my present setup?
Do I ned the 320? with Encoders and 203 with only step and direction?
I was readin up on the 203s and I like these, because they seem to have some very attratvie features in particular on the protection area and current morphing to keep up with differences in motor speed and torque.
5) Recommend cabling adequate for the Gecko drives.
Finally a good schematic of an already proven controller that I can use with my setup. WOuld love to see other home built controllers using the Gecko drives, If you have pictures or reference links etc, please share. I am desperate to get a controller built in the next 3 days as my shop has slowed down and I relly want to assemble my own controller so that I know what to fix when things go wrong. TIA.
