After a two-week hiatus, I'm back to adjust a few things:
- I moved the Y stepper motor driver cooler to give better access to its potentiometer, since it was overheating. Also applied thermal paste for superior heat transfer to the frame. I notice now that the power supply gives a nice breeze of air, I should point that at the drivers:)
- Took off the Z stage and tightened the mount.
- Mounted X and Z stage opto endstops.
- Found some thin metal plates to trigger the endstops.
- Ran some stress tests on the stages. The Y stage has a disconcerting tendency to just randomly refuse to move. Maybe more oil is needed.
- The extruder driver is not currently overheating, a step forward.
- I can get the extruder to heat using ReplicatorG, but the thermistor readings still look digital.
- Mounted X and Z minimum opto endstops.
- Used some scrap metal straps from the new CNC to make the endstop triggers.
These are the relevant config files, for debugging the thermistor problems:
config.h:
/* Notice to developers: this file is intentionally included twice. */

This algorithm causes the timer to fire when any axis needs to step, instead of synchronising to the axis with the most steps ala bresenham.
This algorithm is not a type of acceleration, and I haven't worked out how to integrate acceleration with it.
However it does control step timing, so acceleration algorithms seemed appropriate
The Bresenham algorithm is great for drawing lines, but not so good for steppers - In the case where X steps 3 times to Y's two, Y experiences massive jitter as it steps in sync with X every 2 out of 3 X steps. This is a worst-case, but the problem exists for most non-45/90 degree moves. At higher speeds, the jitter /will/ cause position loss and unnecessary vibration.
This algorithm instead calculates when a step occurs on any axis, and sets the timer to that value.
