PM 728T and 1236T microshop build thread

Hey all, I have a few updates:

1. I ordered some carry master ac300s for the mill and the lathe. They have a 500lb rating each. This is smaller than I would like, but still has 2.5x margin on the lathe, and 3 point contact with 300lb headroom. I picked them because they are short. Short means stiff when the feet are lowered. If this ends up not working well, I will replace them with standard level feet later.

2. Went with yaksawa VFD per this message from mksj:

Hi, I usually would use the WJ200-015SF or the Yaskawa GA50UB010ABA, both are a bit less expensive. The reason I primarily use the Yaskawa VFD's is more flexibly in the programming parameters as well as the programming software is much easier to use. The JOG function in the WJ200 is a bit quirky so requires both the jog input to be active which sets the frequency and a direction input, so either requires dual switches or directional diodes so when the run commands operate they do not back feed the jog. Yaskawa has separate inputs for the jog, it also has a separate E-Stop programable input. A number of other tweaks, but they both work well and have been very reliable. I just did a 1440GT complete system build and used the GA50UB012ABA for the 3Hp motor. No need to oversize a VFD unless there are derating factors. I can provide you with a parameter set for the GA500 if you decide to use it.

I have done this twice, and i will tell you that none of the casters of caster jacks have been anything to write home about and i think my last set was 1200lb rated. there is enough flex in the pad or the swivel mechanism to make the install less that stable. am i worried about it falling over? No is it less than satisfactory stable yes. the solution i found the best is the type that removes the wheels completely from the assembly when it is inplace and the wheel only go down when you want to move it. I have also thought about replacing the pucks in this type with Aluminum.

these work if the weight limits are ok

this does not work well either
