  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Metal lathe options

    Absolutely correct, IMO. People look at the watt ratings of the DC motors in the 7x lathes and relate those to the AC motors on older 9x and 10x lathes (like my Logan 210 with the 1/2 HP AC motor). An AC motor with speed reducing belts and pulleys vs a DC motor with a small (fragile) controller...

    Don't 'take this the wrong way', please! The only thing you are learning here are the limitations of the 7x lathe ! Learning the real machining stuff is all still on MY 'ToDo' list. :)

    Metal lathe options

    Assuming @Chris Cramer is using the stock setup of the change gears, yes. Sure, but I don't know why he would want to do that. Just replace the 80T gear attached to the end of the leadscrew with a gear with a smaller tooth count, and the leadscrew speed relative to the spindle will increase...

    Ball Bearing Collet Nuts

    Ah, I understand now. I never paid any attention to whether the collet was rotating, Other 'one piece' collet types (like R8) that just 'pull straight in' wouldn't produce the same problem. And if you are trying to hold the end mill for sharpening, rotation matters.

    Ball Bearing Collet Nuts

    Don't your ER collet holders have flats so you can put a wrench/spanner on the holder while you tighten the collet nut? Is your mill spindle R8 or Morse taper?

    Prusa mk4

    Learning the slicer software and a few halting steps with CAD are plenty of learning curve for me. :) I'm glad I got the Bambu A1, which has (so far) been 'plug and play' with absolutely no tweaking required- no learning curve at all, yet! There were a few hiccups for the first few hours...

    Prusa mk4

    @Perry - I didn't do a lot of research on the closed box printers, but I think- maybe I'm 'mis-remembering'- that I've read predictions that the P1 is 'at the end of life cycle'. So there may be something better coming down the road pretty soon. Do you have a 3D printer already?

    Prusa mk4

    My A1 Combo didn't have a delayed shipping date; the A1 (without the AMS Lite) did have a delayed date showing on the website. That's one of the things that encouraged me to go for the Combo. (I'm glad I did, the AMS is more useful than I thought it would be.) I ordered on Dec 18 and it was...

    Prusa mk4

    @Perry - I bought my A1 combo direct from Bambu. I think @Janger may have meant isopropyl alcohol (IPA)? It's recommended by some folks online, for cleaning the PEI textured bedplate.

    Here's a pic of the slow feed gears on my lathe - they reduce the feed from .0039"/rev to .0026"/rev. The slower gear sequence is 20-80-15-90.
