I got the 6000 RPM issue resolved. Following another post said to set PD011 to 100 (minimum RPM). Setting it to 0 and all is good.

 

I uninstalled the latest build and went back to 1.0.185 and everything is back to normal.

 

Just a thought. A very nice addition to the lead machine build would be an extension or riser plate that can be added to the c-beam end plates to add the two extra bolt holes for mounting the stepper motor on all 4 corners. Can maybe be sold as an add-on kit to the c-beam end plates. Just a suggestion.

 

I'll add a second enthusiastic vote for offering 4-hole end plates as an option - it's something that's been on my wishlist ever since building my Lead.

I've got some anti-vibration mounts from a previous build that I'd really love to use on the Lead to keep the extrusions from amplifying the stepper noise quite so much (and keep me from worrying about imaginary resonance gremlins), but they rely on having four-corner mounting points (fine, technically it needs two opposing sets of diagonal corners - similar to this - but it amounts to the same).

Right now I'm looking at grabbing some aluminum and cutting my own replacement plates (because machines that can make parts for themselves are awesome), but they won't look nearly as pretty as the OB ones. I still haven't quite gotten the hang of anodizing - although it something I keep meaning to take another shot at.

Has anyone had issues with the Dewalt power lead running parallel with stepper and endstop wiring? Interested before I rip into this. Thanks - Brad

 

If I were to run a universal motor power line through a drag chain, I'd use a shielded 14ga SJT cable like this one: Belden 19364 14/3C Type SJT Premium Shielded Power Cord Cable 300V/60C /10ft | eBay - and I'd still (based on recent experiences ) still shield the stepper cables (only on mains-power heads, 12-48V heads not so much) and other signal cables.

 

Yeah... what I suspected. I'm designing an enclosure. Adding cable mgmt should be easy?

 

Good to know. I'm using Xtension limit switches. Might try both Thanks!

 

Going to test without... but if I get weird triggers/steps... shielding 4 me

 

I designed these on my 3D printer for my LEAD that I am building. The only change since this video is a recessed square for the jam\lock nut to avoid a 2 tool tightening operation.

 

Hi there,
Many thanks to all the pros who help us newbies. I got G Wizard and am trying to configure it. I've got a lead 1010 with the high z mod. I need help with these numbers... (some of these autopopulated so I know they aren't correct).
cheers

Did you post the STL file for these ? Thanks!

 

I havent yet. I will try to upload to GrabCad this week sometime and post a link.

 

Just got ours built and am having some trouble with aluminum. Has anyone tried using a rheostat on the dewalt router to further slow down the rpm? If so...would you say YAY or NAY?

 

HI Rick,

I'm using an 1/8" carbide 2-flute bit. I've used them on aluminum successfully with a much lower rpm motor...but these guys keep rounding down on me. I was thinking about looking into the makita router that can go as low as 10Krpm, but I fear that may still be too fast.

 

Hi Giarc,

No I haven't. What type are you using...I can give it a shot.

 

I cut 6mm Aluminum sheet with my C-Beam Router to make plates for my CB3030.
1/8" (.1250") single flute carbide endmills for plastic - 1516.1250.400 | eBay

Made it years ago... feeds and speeds are in the video.

 

Is there a good checklist out there of what maintenance should be done after a big job? Tramming? Making sure machine is square? What else am I missing? Any preferred way of doing all this? Cheers

 

In the video, did I miss how to install the cable tray (20x20) part that runs along the gantry for the cable chain to sit on? What am I supposed to be using?
Edit, Never mind, I found it. It's circa 1hr 25min

 

Hi all,

I've been following this great little CNC for a quite a while now and been gathering parts to make it one day.
Through my quest for parts I came across many kits and parts from the East, but in all cases, Openbuilds was clearly mentioned as the designer/creator of this machine.

Until yesterday I run into this UNBELIEVABLE guy. He has even inserted watermarks with his company logo in the original openbuilds photos. He even copy-pasted the text replacing the Openbuilds with his name:

".... The Lead CNC Machine is the result of years of experience, feedback,and suggestions,and through rigorous beta testing and staying true to the modular nature of YuYong 3DMaker Linear Rail system."

I did not want to put a link here, you can find it yourself in the aliexpress....

I was really annoyed and angry!
How do you guys deal with those copycats? Surely they can not be left like that!!!

 

Has anyone built any solid plates that can utilize linear rails or wheels for the xy gantry plates so you don’t have to use the two separate plates with wheels with the attached vslot rail? I hope my terminology is correct, just getting back into this. Any new thoughts or plans/designs on a more solid or stiffer design for xyz axis beams?
Just curious if anyone has experimented with anything that would make machine more rigid. Or would adding the additional wheels suffice?

Is there another area on forum that has just upgrades to existing kits or am I in the right place?

 

Hi, do this mean that my shipment will ship today? I am waiting from May 20 then on May 29 they sent to me the track number.
