Hey Guys, Not trying to step on any toes, but I have noticed lately that some of the messages are getting rather lengthy because they have not been trimmed. It would be appreciated if you will do a

Re: Which not-so-Mini CNC mill #mill
Hi Carsten, I have been using a Stepcraft 420/2 machine for "pcb" etching for more than three years now - with a great deal of success. Having bought the kit (currently about ?950 or so I think) and

Re: Which not-so-Mini CNC mill #mill
Hi all, at the risk of slightly hijacking the thread: Are there any specific recommendations for a *slightly* higher-class CNC mill? If going from the initially asked US$200 budget to, say, $1500 to

Hi I tried to make suction/vacuum plates with styrofoam and it works quite well. It is easy and quick to make, once the drawing has been made it just needs a soft rubber cord. I even milled small

Hi, I use doublesided tape to hold the PCB blank down and two 1.5mm diameter pins through the board to ensure top and bottom side registration. I use Autoleveller (freeware) as the height mapping

Re: Which Mini CNC mill #mill
Use level mapping. Still in project, I am trying to make a vacuum bed that allows perforations.

Re: Which Mini CNC mill #mill
I agree that height mapping would be a good thing, but I don't have it.? I hadn't thought of indicating my fixture after I install it but before I fly-cut level it.? I can't get to this for a week

Re: Which Mini CNC mill #mill
I keep seeing this post about getting your bed flat. I don¡¯t even worry about it. I get great results using the height mapping routine in candle. You cannot trust within .05mm a flat bed. When I

Re: Which Mini CNC mill #mill
how did you get your bed flat?

Re: Which Mini CNC mill #mill
when I put the fixture on the table there is no way to assure that it will be level. I don't have to surface it between boards if I don't remove the fixture, but i use the router for other projects

Re: Which Mini CNC mill #mill
I get good results using very thin double-sided sticky carpet tape to hold the PCBs down for milling. Dan Staver Tave Tech Corp. 3130 Hollycrest Dr. Colorado Springs, CO 80920 +1-719-359-5352 - office

Re: Which Mini CNC mill #mill
If your pcb's are always the same dimensions, you can add vacuum to the hdpe (or delrin) holder, that way you do not need the screws and the vacuum overcomes any board warping. No need to resurface

Re: Which Mini CNC mill #mill
Maybe there should be a subject change.? Have a look at the two fixtures whose photos I've attached. I make printed circuits which are about 2 inch by 3 inch. I found that I couldn't get reliable

Re: Which Mini CNC mill #mill
Yes but don¡¯t expect anything fantastic for the price. These do not have a single piece of industrial grade componentry on them, and rely of the fact most people are happy to continually fiddle with

Re: Which Mini CNC mill #mill
John S. Thank you for your information. I understand what you mean. I have done on 3d printer to put it together. There were some missing parts. Can you tell me more about the good spindle? I found

Re: Which Mini CNC mill #mill
Use Eagle, pcb gcode, a cnc diy with ball screw, before spindle of 500w, now of 1.5Kw, bCNC with autolevel.

Re: Which Mini CNC mill #mill
I use Eagle with the gcode plugin - a (ULP) for Eagle, and a SainSmart 3018 which is just like the one you stated above. I use Candle to control the 3018 with a 20 degree V bit and this is my result.
