→Todo List

== Todo List ==
* Documentation
* Documentation
Squareness todo:
* Physical end stops - probably want to move the wiring out of the X axis tubes for this
* Limit switches on A-axis (slaved to X, the rail against the wall)
This will allow both manual squareness and automatic machine homing. Mach 3 has a routine that will home the X axis with the slave, then adjust which ever one did not hit the home switch independently.
Water table todo:
* <s>Fix 2 pin hole leaks (one at each end of tank)</s>
* Better drains (one drain hole per square in the base of the tank all plumbed together with a single drain valve)
* Fit bladder input line on the side of the tank (so it doesn't collect crap in the tank)
* Wash out old compressor tank
* Trim the top of the side where the A axis hardware grazes the top of the tank.
* Paint the outside of the tank
* Treat the water with the green goo (last once everything else is complete in this section)
Plumbing/wiring todo:
* Extend air line to under table to create a manifold for table mounted air consumers
* Run large conduit for 220 outlet for the plasma cutter
* Run small conduit for data/estop between the table and the PC
* Run black pipe for connecting the table to the bladder (old compressor tank)
* Water line from north side of the shop, with input into the old compressor tank
* Air lines to the compressor tank (one vent on from the compressor)
* Run ethernet line to PC so its not on wifi any more
* Z axis limit switches
Plate marker todo:
* Design and cut new y-axis trolly or offset plate to carry torch and marker
* Machine mount for engraver
* Mount new trolly with air slide and Z axis
* Plumbing and wiring
* Pen mount as well as engraver?
35A Fine Cut todo:
* Build floating Z axis using left over linear rail
* How to multiplex the digitise input for touch off? Relays to switch digitise input from ohmic sensor to switch on head? (and disconnect the switch from the z limit array) (the switch should be in the z limit switch array by default incase the THC plunges the torch into the work piece)
Roundness/cut quality todo:
* Remove and clean X axis gears, reinstall and use loctite on set screws (the keep backing off)
* Make sure all bearings are right against the rails so there is no slop
* Investigate backlash and configure mach3 is required
* Get quote for installing ground rod next to the table and execute it
* Look into THC issues (cut rippling) if still present after ground rod
* Why is the THC seeing ~80V for a good clean cut from the hypertherm? Is the internal voltage divider broken (is this why the machine was retrofitted with a dangerous high voltage tap?)? Or is this related to a bad ground at the table?
* Motion pauses: (Seen on large 3'x2' complex cuts)
** Do we need to add a CV on G-Code in the preamble of the post processor
** Smooth stepper under-run errors - I have only seen this when jogging not cutting, mostly related to rapiding the Z, maybe reduce the micro stepping on the driver for the new threaded drive step count is huge per inch which could be hurting us
** Axis and Core frequency tuning for the smooth stepper?
** Look ahead tuning
** Is CV plasma mode hurting us?
** System problems, AV jamming things up?
Ohter things:
* Cleaning/maintenance schedule
* Shelves/lockers in the unused space under the table for project/tool/etc storage?
* Materials storage ideas?
** sheet goods
** 20-24' bar/tube stock
