  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is 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!

    Motion when locking the axis

    But that's exactly the problem: the table on Y is almost sticky yet it's loose side to side i.e. not rigid enough. What I'm trying to find out is why this is the case: is it because the gib height is too short and is not seating correctly or seating at a non-coplanar angle or wether the gib...

    Motion when locking the axis

    Yes I realized that I didn’t answer many questions. I wanted to take time to compare both the x and y gibs and take measurements and at least blur the gibs against a surface plate to make sure they are flat and report back to the group.

    Motion when locking the axis

    Totally understood and I appreciate the additional explanation. When the gib lifts in the green/front/wide end, it’s hard to tell what’s happening around the blue/back/narrow end. It seems to move but not by much. So as you said: it could be pivoting somewhere near the back or center, the gib...

    Motion when locking the axis

    Didn’t mean to imply short in the taper direction, I know it wasn’t too short since the gin was making contact with the 2 screws. I meant short along the dovetail as you’ve shown the drawing. Hopefully the blueing will confirm that the gib is just not tall enough as you suggested and shimming...

    No the gib is in one piece, I already took it out for visual inspection and cleanup when I received the machine.

    Motion when locking the axis

    Unfortunately PM support initially said that this lift was normal and only agreed to send the replacement gib blank after I stated asking more questions and challenging their logic. I asked about clearances and taper angles but they didn’t have any of this information which is what brought me to...

    Motion when locking the axis

    @RobinHood I'm so sorry I thought this style of tapered gib setup with the front and back screws was more common so I assumed everyone knew what I was referring to by snugging the gib in place :) My procedure for setting up the gibs was to push the gib in using the front(thick end) screw while...

    Motion when locking the axis

    @RobinHood @Dabbler thank you so much for the valuable insight! This is the kinematic setup I created in fusion360 to try and understand the root cause of the issue(if it's indeed a significant one). The blue and green components are the sides of the dovetail(of course for simplicity I...

    Motion when locking the axis

    I’m totally on board with this approach, I’m just not sure what else I need to do to figure out why the gib is skewing in place as shown in the video other than blueing it. Also based on what PM support told me, what they shipped is a blank: a much longer piece of grey cast stock with the...

    Motion when locking the axis

    Believe me I felt the pain of brokerage fees from both FedEx and UPS before, I totally get it :) This is not in anyway PM’s fault. I called CBSA and they said the Mississauga branch where my package is had “severe infrastructure issues” and to expect 2 additional weeks of delay…shame on our...
