Thanks rodw, I had ordered a DM542 from Steppersonline and it arrived today. Even with the 24v and 270OZ stepper and DM542 set at 3A I now have plenty of torque. Problem solved. I guess the TB6600s weren't up to the task.
Great to hear. I really don't know why people ever recommend TB6600's. They have been known to be cr@p for years.

There is more on the table yet! Have a look at the green and red lines here showing the torque difference between 24v and 48v for a 3.2 amp nema 23 stepper

The temperature rise was a max of 60 deg C (40 deg in the graph) so still at a very safe level.

Great info thanks. I will most likely go with the 48v supply I bought , although I will then have to add another step down supply as the board max is 24v so I will need a 48v to 24v and then 24v to 5v I already have. Worthwhile though going by the graph. I don't expect to drive at high speeds either.

Generally people use separate power supplies. Something like a Meanwell MDR-60-24 24 volts and a similar one for 5 volts. Meanwell MDR-10-5?

These are not expensive.
