From: "Art Eckstein" <a_eckstein@...> ... stepper. ... Hello Art, that depends on the material of the permanent magnets and the design of the motor....
Hi Art and Bene, I have fitted a number of stub shafts, hold the shaft in the chuck and support the motor with a fixed steady, drill and tap into the rear of...
Hi Art, Bene and Greg. Take a look on Renco web site: http://www.renco.com/106038.htm Bonding and Debonding Instructions for the Modular Encoders Leo ... ...
Anyone put a variac in front of their transformer to get optimized voltage? Any examples to build an energy dump into power supply? Dirk calico888888...
Note that he said "in front of your transformer"
I don't there would be any controversy about this, as long as "your transformer" is an isolation transformer....
Thanks very much SJH This seems like quite a project to me, I can program in C but know nothing about the rabbit processor and less about white heat. ... ...
I would have thought that using time increments of 2ms or even bigger would be fine. Most controllers, the G-Rex included, eventually break any moves into line...
I agree with Les. The conversion from euclidean coordinates to strut lengths is non-linear, but still a very smooth function (technically, infinitely...
That's a good point although the whole point of my machine is extreme speed, >>400ipm. I have been down the route of preprocessing, I did this by splitting my...
Depending on your software skills it wouldn't be difficult to write a front end for the g-rex that does the preprocessing. If you want to jog in a straight...
My speeds are going to be in the region of 50M/min even straight lines have to be split into segments in a parallel machine and your deviation from the correct...
I'll bare that in mind, thanks. for jogging I could certainly live with slow feed rates and a delay, my fingers are not fast enough. it is fast! Graham p.s....
... The answer may be to analyse the machine to work out the maximum linear segment size which deviates less than a specified amount from the true path of the...
... I guess I was just thinking that the approximation would fall down as the machine will never actually follow the spline. ... It is for only two axis and...
I've a Hengstler encoder RI 58-D. Can I use it with G340 because it has 10-30V supply voltage? 24V is easier available. I understand resistor between enc+...
I got this problem when I play reverse, mostly skip steps. I switch the motor, they are fine. just one Axis that give me this problem. anyone ever had this...
Hi Pave, i suggest you connect the encoder supply to +24V and a pullup resistor of 1k Ohm from each of the A and B outputs to ENC+ (+5V) at the geckodrives. ...
Hi Rud, So others can find a solution in the future... What was the cause and what was the solution? Jim... ... __________________________________ Start your...
the couse was, the pin assignment somehow was using by others, not sure which one (mach2), got to read the manual. so I just change the pin. problem solved. ...
I have 2 stepper motors with 0.5Ohm Winding resistance (3.2V) 2.5mH. I want to connect 2 of them in series for a special purpose machine with 2 wheels. (No...
Nov 4 Update: Here's what's been tested and works as of today: 1) Acceleration. This sets the axis rate of acceleration Syntax: A(axis)(value)<cr> Axis =...
Cool stuff. Some questions and comments mixed in below. ... What are the units here? Steps/sec^2 would make sense, but that could be a huge number (which...
Hi Mariss, ... If for example X is the master axis then I assume that it is up to whatever is supplying the code to make sure that it's acceleration and ...
