Yes I have been to Yuriy's site already and plan on making this for my lathe so only need X and Z.
TNX Jeff for the info. Looks like I can use a Dremel cutoff wheel or take 2 pieces of wood and clamp (lightly) the scale in between and use a hacksaw to cut the scale.
The wood being clamped would...
I have read on some eBay ad's on these unbranded iGage DRO scales (Shahe made?) that you can cut the scale to custom lengths.
Is this true? If so what is the best way to cut them? (fine tooth...
I have a FC system on my mill for 2 years now. Had some great customer service at first with tech named Tyler Hart at FC. However lately
they have been ignoring my questions and have learned that...
Yes I see there is a difference in the KBelectronics controllers. The one I originally bought is a SCR type and should have been the PWM and then maybe
the motor might have run much cooler. I have...
So after some searching using treadmill motors and VFD's I found a reasonable priced VFD and 3 phase motor all for $280.
The controller I was using was a KBIC model and worked ok but will be...
Can you point to what has been said about using treadmill motors? I remember reading on some forum (here? don't remember) a description on their efforts in using a treadmill motor for
a lathe they...
Thanks for the info JD, but for $995 I think I will keep changing the belts. For that price it isn't worth it for me on a lathe
that is hobbyist at best, need a cheaper solution.
I have a CB-1220XL lathe/mill that I use strictly the lathe, I removed the milling head since I have standalone mills.
In the past I did some research on converting the AC motor to a variable speed...
Try using search terms of "missing steps" on this sub forum and see what others have experienced.
Yes, the driver chips and opto's may be genuine but it is the way the board was designed. If you look at the data sheet for the driver chips whom ever in China designed
the board did not use the...
I have a CNC 3020 that i had problems with as your seeing now. It turns out the driver electronics for those Chinese machines are garbage.
What your seeing are missing steps and what i did at first...
Ok, so poking around here I found a link that has all kinds of DXF's etc. and sure enough there was a DB25 so I have that now but
in some reading at the Cambam site I liked Jeff Birts idea of a...
I have a question that I haven't found an answer to in the CamBam documentation on how to import an object like say
for example a DBxx connector that will be milled out via an inside profile? I see...
Oh forgot to mention that I mounted the fan inside of the cabinet at an angle that pushes air against
the back of the G540 for cooling.
I haven't found one either but it isn't difficult to make the replacement.
What I did was keep the power supply and spindle motor the same, mine was working ok and hasn't caused any
issues as of...
12,700 steps per inch.
But need to increase the velocity from where I had decreased it. A bit too slow. I don't have
the acceleration or velocity numbers handy.
I have one of these routers, the 3020 and found out that movements on all the axii had some missing steps as has been reported
on this forum.
So I decided to do the filter cap mods as described...
Thanks to all that replied. I had the feeling the G540 was fixed at 10 microsteps.
Reason I was asking I was having problems calculating the steps per inch for this engraver I have and couldn't see...
Wow the responses are overwhelming!
I checked the manuals on the Gecko website for the rev's that were shown and they all say 10 micro steps.
Have all the rev's to the G540 (rev 1 to rev 8) always been 10 micro steps fixed?
Thanks,
Bruce
I have one of these Chinese CNC machines, a 3020 is all I remember and have looked through the forum looking for info
on some issues I have been experiencing with this router.
I have measured the...
Thanks for the info CS.
I did get this solved by Tyler at FlashCut who I think used Fanuc post processor and then modified it depending on the errors generated by Flashcut on my g-code.
Even that...
Using CamBam and finding it is easy to use. Nothing intricate just a bunch of 2D stuff so far.
But I have a new mill that uses Flashcut controller and in the past used Mach3 on a different setup so...
Thanks for the info Art.
After I posted this I went back and did a search just on the RF31 and found out that the bolt patterns were different between machines so I understand the problem
with kits...
I have a Rong Fu RF31 mill/drill and am considering converting it to CNC use.
I have checked out a few CNC conversion kits online but most don't mention the RF31, except for MicroKinetics site they...
Yes, Andy came through so I am fully registered on CamBam.
Sorry to post this here but I have no other way to try and get the attention of the admin for the CamBam UK forum. (Not this forum on CNCZone)
I registered nearly a week ago and still have not...
Trying to get my head around these servo drives. So the way this works if I have an encoder that has 384 pulses and since it has
2 channels you have then 384 * 4 = 1536 PPR(evolution) of the motor,...
