Latest beta of CncUsbController, from CNC USB controller can import correctly gerber files for PCBs. I have tested the feature only once, but seemed to work ok.
there may me some other...
Cadsoft Eagle could help you to draw a correct schematics, create a board according to the schematic, and export a g-code file from your board.
In Eagle, plugins are called "ulp"s, are in c-like...
if you pay attention at 2:53 in the movie, to cut a full length line, the cake is rotated 180 degree in the middle of the line.
So it seems to me that to cut 24" line, the table needs a lot less...
For R6 it should be simple: circle is tangent to the vertical line.
for R114... simply there isn't sufficient information.
Eagle. use the latest version to be sure that files are opened properly
I have attached two versions. I have used the one with SMDs.
no, there is no chance in using USB/parallel adapter.
But you could use (with far better results) a CNC USB controller. All of this controllers uses microcontrollers that must be programmed prior to...
imho, for hobby, this are exactly the needed components. It will not make a perfect machine, but the builder will see where are the weakest points of the structure.
It's easier to first drill and then expose the board to UV :p
1. why not using the original tape head? if it can read audio frequency (20kHz). If I've made the computations right: 20kHz with original speed of 5cm/sec means 1 pulse/2.5um - way lower than needed...
all inkjet printers do have linear or disk encoders.
None of the laser printers have such thing.
I like your idea, It should work if the magnetic head/sensor can work at very low speed.
see my version here: http://www.etc.ugal.ro/sepure/projects.html#proiecte_rezolvate
voltage will never create heat, current will!
So I think that you have set the current too high for that motors.
(It may be a resonance problem too, but I doubt)
Wouldn't be this the reason ESTOP was invented ?! :rolleyes:
Just found this link CNC to draw tattoos and wanted to share-it.
Page is in Russian but pictures are universal.

sounds similar?! :D
here is my approach. (circuit and currents on R_shunt)
what about soap? I never tried, but it should work

do you think that this urethane will allow milling some Al?
on PCB, MDF and plastics it will work for a long period of time, but for aluminum will be higher forces in the nut...
What about abrasive...
I see no trace of this new IC in Europe. At least for now.
Driver is build at home?
What's the value of TBA? (R2 and R4 in schematic)
I have nothing about this country... I'm against people that govern-it... in such a disastrous way for the people. We see everyday luxury for governors, and poverty for people... I (1 man) can't...
from the A4983 datasheet, the "output ON resistance" of power transistors is about 0.3ohm. Let's do a simple math:
2A/coil = 2A in the power transistors;
there are 4 transistors/coil, but
only 2...

if the motor is like the one pictured in the first page of the thread, then it's a 3 phase motor. The controller will convert the DC voltage from power supply to a variable frequency 3 phase AC to...

I think it will work with cheap acme too.
I like your idea.
It's the cheapest R&P solution you can use, and seems to work just right.
It was one of the moments "why I didn't think of that?!!!"
