What are your acceleration parameters?

Also do the stepper motor current limit adjustments. Did you oil and manually spin the wheel bearings?

I thought you would make the molds, reclaim your aluminum old beer cans, pour the cast, and machine the surfaces. Expect raw parts by 9AM  and finished parts by 5PM tomorrow.

Just pulled the trigger on purchasing one of these mills.

"I have no idea what mildew ridden salt pit some of these fans came from, but mine was from one of them."

Easy answer: China

T2 Engraving / Re: Linux support?

I have written my own linux application. Have also written my own firmware (for stm32f chip) so I am no longer sure  what standard GRBL it plays with.

The wires are readily available in various lengths. Connectors are same as used on the typical Elkes Maker but the pin mapping can be very different. I found that the connector to the motor is easiest to reorder with simple hand tools.

I have printed and given away at least 50 slate coaster. Only one person I know of is using it as a drink coaster and he is a slob. Coaster looks like it went thru a pig sty. (perhaps that is unfair to the pig)

T2 Engraving / Re: upgrade again
« on: July 16, 2017, 07:04:41 AM »
I have the 5.5W purchased about a year ago. Currently building a a 500mm x 500mm machine and going with the 2.5W laser as the 5.5W will not focus to a sharp point. It takes me about 10 passes to cut 3mm hobby grade plywood with a z-axis. If the newer 5.5W (or hotter) modules work that would be great.

I have been following your discussion closely. Do you think it is usable for light milling/etching and more importantly drilling 8mm aluminum? If so:

  1. do you have a recommendation / warning about any specific vendor
  2. required add-ons for a non-machine tool user (no cutting tools!!).
  3. vendor upgrades.

General Discussion / 3d printer hotend problems
« on: July 13, 2017, 09:44:20 PM »
I recently purchased a Monoprice 3d printer. Believe the actual manufacturer is Wanhao. Have had very erratic results. I have suspected that the unit was running very hot as I had best results with PLA at 185C. Borrowed a thermal scanner from work and did some measurements. Both the hot bed and extruder were hot.

The bed was set at 50C and measured 78C.

The nozzle was set at 200C but was I unable to get a consistent reading. The displayed temperature was jumping from 170 to 215. The thermal blanket around the heat sink was smoking. Took it apart and noticed that the thermistor was hanging in air. Should have been in a cavity in the heat sink. I was getting better results with an enclosure.

Also, the heater element has a set screw to hold it in place but it was lose.

Time to order a spare set of hot end parts

The 3D printed adjustable belt anchors are great.
