Hi there, We have noticed that our casting on this 2007 cf741s rip fence is massively out of square. Is this by design?? Thanks Simon

Joel,
Are those black things on the ceiling sound absorbing panels? ?
Thx,

Re: 3 phase high leg placement
Hi, the issue is to determine which 2 phases the control power supplies for the machine are connected to, you want those two lines connected to the non manufactured line of the phase converter.
If you have a true digital phase converter (rectifier/inverter) then it doesn’t matter, if you have a rotary converter it does matter.
You can check the drawing for your machine however I normally use a DVM to verify it.
1) unplug the machine, or open the breaker in the distribution panel
2) using AC Volts on the meter verify that you have no power in the machine
3) close (Turn on) the disconnect switch for the machine
4) using Ohms function on the DVM measure Phase A to Phase B, Phase A to phase C, and Phase B to Phase C
5) only one of those pairs will have continuity, maybe 10 to 100 ohms, this pair is the one with the control power supplies, it must be fed from the non manufactured line
6) you now need to either one of the control power leads in the machine to the non manufactured phase or reverse one pair of phases in the machine plug (doesn’t matter which pair)
7) If your machine motor goes backwards after changing the plug above, interchange one pair of wires going to the motor to reverse rotation, it doesn’t matter which pair.
Regards, Rod

Re: 3 phase high leg placement
Chris i had to change the high leg on my F700z but cannot for the life of me find my notes. ? If you call tech support in DE they can tell you which leg it should be on - when i got mine they asked me to check it and said it is common for the factory to send new machines with the high leg on the wrong terminal.? Mine was so it was a quick change
Thanks for that, Mark. If anyone has machine specific info for high leg placement for the RL160, F700Z or Exact 51 please let me know. Thanks?

Yes, the "manufactured" leg is the "high leg".? Brief summary of the issue here.
We typically refer to the three phase conductors as L1, L2, and L3.? Assume L3 is the manufactured leg.
1) Motors only "see" the voltage from one leg to another, so it sees three voltages:? L1:L2, L2:L3, and L1:L3.? In an ideal system, these three voltages are 240V.? Note that there is no "high leg" here from phase-to-phase.? ? Normal utility supplied power is "ideal", as is a Phase Perfect converter.? Rotary phase converters are not ideal, and you will see some voltage variations between L2:L3 and L1:L3.? However, on a quality commercial (vs home made) rotary, the variation will not be enough to bother the motor.? So machines that only have motors and simple switches are unaffected by how the legs are connected.? ?I
2) The "high leg" is not a reference to the voltages between the 3 phase conductors, but rather to the voltages from a phase conductor to a neutral (if present) or to ground. Since motors don't use neutral or ground, this doesn't affect them.
3) Some things other than motors, most importantly electronic controls, can be sensitive to voltages out of standard range.? ?So on machines that have such things, you want them to be connected to L1 and L2 (these components don't use all 3 phases)? Hence manufacturers identify which of the phases are good for controls and which are not (ie, say connect the manufactured leg to brown, etc)?

Re: AD941 dust hose attachment
I don’t know what filament Bill is using, but I’ve used Hatchbox PLA almost exclusively. Done a few parts for my car out of ABS due to extreme heats here in AZ, but mostly PLA for the shop.
