Can pneumatics partially fire? Meaning fire but not all the way? Because if they can I think it would be cool to attempt a pneumatic lift.
No they can’t.
Here is an example of the best pneumatic lift built in VEX.
Most of the images are down so I would look here

Just grabbed a couple of the important pictures.
Do you know how heavy that was? 4 pneumatics tanks must be heavy.
I think it was probably around 20 pounds. He also had an 8 motor drive so don’t go feeling too bad for him.
Also here is video from original thread.
Honestly, this is one of the few robots that I will consider it as truly groundbreaking.
If I am not wrong, this is the first, all-pneumatic lift system.
PS… the rest in my list of robots that achieved groundbreaking status:
- 1103 and 44 (Round-up)
- 2W (Gateway) - the 1st wallbot
- the NZ bots (Gateway) - the rising of 6-bar and side-rollers
- 8059A (nbn)
(I am even tempted to include one of my 8059 gateway… the 1st dr4b 
)
