Holy crap 1,5kW servo. That is huge on on hobby size macine. It can some serious damage! Just gear it down, you will not need any couter weight. You need HW limit switched and one brake on lead screw to prevent the head from dropping when you power off. Pekka |
| NeoTech:
Ah well its not a hobby sized machine it will be about 800 kg and half cubic meter of work area. And yes the driver takes hw limit switches and home switches Linux cnc take signal on the field bus as well so i will piggy back the hw signal to the field bus. :) |
| NeoTech:
So spent 3 days tinkering with the tramming possibility.. So basicly, 22mm holes, with a 16mm bolt, head is sitting on a 60mm dowel, and has a little "cam" that allows for tilting the head ever so slightly. That cam only has about 2.5mm radius, so it will not allow for alot of adjustment, but enough i think. |
| NeoTech:
So while waiting for the handymans to complete my new workshop floor, i continued making drawings.. Molds for base and pillar, so i know how much sheet will be used.. |
| RobWilson:
Hi Neo What do you reckon the column casting will weigh ? Rob |
