Here are some of the first parts made with our new upgraded mill which now runs with ballscrews and linear rails. Top speeds as well as accelerations are up on all axes, and there's very little risk of losing steps any more. Hope to have the servo electronics ready sometime in May... Jari also made … Continue reading First parts with ballscrews/rails
Now that we have the new spindle on our mill, and the linear rail+ballscrew conversion for the Z-axis have been working for a while, it's time to upgrade the X and Y axes. Jari has made some good progress on the table/X-axis. The IKO 15 mm linear rails are mounted, we've machined and attached the … Continue reading X-axis progress
I've bought three 19" rack enclosures from fellow cnc-enthusiast Jiri K: My plan is to house the PSU, based on a 230 VAC to 2x30 VAC 1.8 kVA transformer, in the bottom box (I might have to extend the encolsure a little, the transformer should the same as Sauli J:s transformers, about 220x220x120mm). The middle … Continue reading Enclosure for servo electronics
One part of our continuing CNC-mill upgrade is to connect a jog-pendant to the mill which will enable jogging and some other manual controls in EMC2. Here are some pictures and notes of the present status.
Today I got the whole motion control chain from EMC2 on the pc through the Mesa m5i20 servo-card, homemade optoisolator card (far right), PWM to analog filter (small board on the right), servodrive (middle), powerstage (middle left, with heatsink), through to the motor (left, a Sanyo P5 1kW servo) working ! This is truly Open … Continue reading First Steps With Brushless Servodrive (Microchip dsPIC + IRF IRAMS)
Spent today milling a new motor mount for the ABB motor we are planning on putting on the Opti. Here's the raw material, a 120x20 mm aluminium bar. The 6-flute 6 mm endmill we used is visible in the left upper corner.
