[C axis mode slow]

My mistake; I thought I remembered it working like that.

[Laser Pulse Control with Power PMAC DSPGATE3]

How are you getting stuck, exactly?

 

If you want to use usrcode.c, make sure you right-click it, select Properties, and set Build Action to Compile. Otherwise, the IDE will ignore that file.

[C axis mode slow]

As bradp suggests, set those parameters properly (the defaults likely are not what you seek). You may consider setting both ta 0 ts 0 such that InvAMax and InvJMax dictate acceleration duration instead. I'm assuming you chose ta 1 pretty arbitrarily.

[Reading an Encoder]

You can compute (EncTable[n].PrevEnc * EncTable[n].ScaleFactor). That's fundamentally the same as Motor[x].ActPos if I recall correctly.

[P variable value on power up]

There is actually an easy way to initialize all P-Variables to 0! Use vscale.

 

For example to set P0 - P65535 to 0 at powerup:

 

L0 = vscale(0,0.0,0,65536)

 

 

Fundamentally, this just multiplies all P-Variables by 0.
