no body here asked anything close to a question that would get that reply so why did you post here??

trying to get your post count up so you can post spam??

LOL its a $900 CNC made in the cheapest way possible with the lowest grade components and cabling and your astonished that the engineering and design of the boards are crap???????????

that is easy to to fix by going in and turning off power saveing and editing the power profiles of the USB / LPT port to not go to sleep and in to low power mode

but i still wouldnt use a laptop...

Yep i am still around

by the way a 6040 isnt 600mm x 400mm

its ment to be 600mm x 400mm work area but its not its at most 550mm x 330mm and the unit is(with the steppers sticking out) about 750mm x 520mm allowing a...

no matter what way you put it other than the way it was made to sit you will be putting stress on a joint or component that was not made to do that and you will damage it

the only way i can think...

there is a little program i use to look at the GCode

GPlot1.3

338530

yep

he even said "I don't have an accurate way of measuring distance moved apart from a long steel ruler." so we know he has one

i even explained (WITH A PIC) on how to do it and what you do...

this is also why i said to do the testing over as long a distance as possible because any inaccuracy you make over a longer distance is less %

1mm inaccuracy over 500mm is A LOT less than 1mm...

1 of 2 things i am guessing

1:- there are trim pots on the G-540 for each channel

2:- you put in to bigger limiting resistors in the cables for the steppers



if you can measure with an...

1:- i dont that way junk wont stick to them

2:- make a test Patten (like a big square and a circle in side of it and make it at lest 2/3 the size of your work area) then run it (in the air not...

why not just use the auto tune to set the steps?
336570

then just do what it askes

cool where did you find it in kit form?

rods not rail's but the difference in price isnt that much 10% at most (in the suppliers around here anyway)

yes

on a new unit there should be no backlash
the unit i have is 200 steps per...

hmm looks ok but a few small things
$2,199.00USD??
my YOOCNC 6040 has the same working area and was $700AUD ($980AUD to my doorstep)
granted i have replaced the controller and the cabling and that...

and another thing you have to remember is
"never believe a testimonial for a company that is on there own website"\

do some searching for your self

that is the way 90% of the units where delivered nothing new there

there looks to be more than just the wrong bearing there but here is the diffrence in bearings

left is normal type right in what all ballscrew's should have at lest

324164

its called using normal every day bearings 5 for $1 (most likely roller-skate ones 602 i think) instead of the correct $30 each bearings that have no backlash there are ways to reduce the backlash...

make a file that runs a big square and make it cut down about 3 mm or 1/8" and keep at about 0.1mm cut depth run it at max speed you can and keep turning it down bit by bit till you dont lose any...

but where Aussies here no milk Beer and prawns mate

LOL isnt that the truth

Aussie why? u an import :-) just like everything else in Oz

no but the cables to them act like Antenna and collect noise and feed it to the controller

controller end and both on the spindle<->VFD to earth the mill frame

wholesaleneon while the G540 (i have one) is a grate unit it requires you have a LPT port (printer port) on your computer and that is becoming less and less possible as there just not making mother...

i use
Google SketchUp to draw in

add-ons of SketchUcam to setup and generate the gcode with mainly 2.5D but it can do 3D stuff

to run the Mill i use Mach3 and would like to have a look at...

ok if that is the case here is what i had to do to my 6040
1:- replace controller with G-540
2:- replace all stepper cables with grounded shielded cables
3:- replace the VFD <-> spindle cable with...

i have already been down the self build route but not for me for a friend

here is my build / rebuild thread almost everything i did is in there with some pics
