When my mill conversion is complete I will remake the 3d printed parts I have designed and printed for my printer

Will have to post pictures of my printer. The thicker y axis piece is 20.4mm thick and took about 3 hours . Started with a prusa i3 before I modified it with open build extrusions

Here is the Y axis mount and spacer based on Hoss machine cnc conversion

I am hoping to get my Harbor Freight mini mill converted and able to cut replacement parts for itself using 3d printed parts.

I purchased ball screws, 479 oz dual shaft steppers, etc just can't...

Normal threaded rod can be used won't be the fastest moving but will work as a proof of concept. You have to calculate the steps per inch based on the rod you use

Securing the material being cut I...

Since it is an open system how about running the output of the cooling line into a funnel filled with filter material ?

What kind of endmills HSS or carbide? I used a few HSS but found they dulled fairly quick. Switched to solid carbide, they seem to last forever.

You should be able to watch the diagnostic page (where all the input/outputs are shown) in Mach3 (not by my CNC machine) and see if the output changes, sounds like something is toggling the dir...

Is there a bushing/bearing in the wooden box?

Remember triangles are your friend when trying to strengthen something. On the front and back to the upright you can tied a brace to the U-channel base and to the table top (one or the other should...

I would assume it refers to the folded edge... like the hem on a pair of pants. Rounds off the sharp cut edge

Anyone able to open the vector 101.zip? I see 47000 pages of symbols

I guess I would position the holes using my router to center a smaller hole. Then step drill the using a drill (hand or drill press if the part fits) that way the holes are layed out accurately.

Does the analysis of the torsion box also include the inner ribs and skins on all 4 sides? In the pictures it appears to have an open front.

My first test of a torsion box had 10 ribs vertically...

I think the cable you are looking for is a 25 pin connector serial cable

Should work great for you.

I am in the process of rebuilding my X rails (modeled after the JGRO) no support and getting alot of sag spanning 52"... also trying a new design for Z. Then I will...

I drive my 52" X axis from the middle and had trouble with racking. I picked up some 3/32" steel cable, pulleys and turnbuckles and did the following

The cable runs from 1 side of the gantry (the...

Is that video at normal speed?

Why does everyone want to put music on their video? I like the sound of the steppers and router.

Speed might not be much of an issue on a small router but 4'x5' at 30 ipm will take a LONG time mov from one end to the other.

Like alot of people here and I am sure more will tell you.. Gecko...

disable the nic.... I had issues with my EMC box with the nic enabled. ended up swapping it for a wireless card

Solution.....

Went to TigerDirect bought a Trendnet TEW-441PC wireless adapter for $30. I had spent 3+ hours trying to get the Netgear working only took maybe 5 minutes to get the other card...

My answer is 106

I installed EMC2 (2.2.2.1) then updated via the update manager. When I run a latency-test with the network card disabled it is under 15,000 BUT if I enable the nic it jumps to 30K-51K and jumps...

I have my router working with Mach3 but would like to see how it performs under Linux. Has anyone come up with a guide to take the configuration info in Mach and move it to EMC?

If not I guess I...

Just remember to OPEN the window first....:o

When I made my first AB nuts I used part of a cutting board (possibly HDPE). Toss the part in the freezer over night then retap it while it is still cold

How about starting with some molten aluminum then adding the chips to that?

What about a water filter like the drywall sanding system? Basically a bucket with a lid, attach a shopvac to one fitting (above the water line) and the sanding pad and hose to the other fitting (end...
