1st Build, Second machine

[m.marino]

Had to cancel the online order from Maplin as it would have not been in stock till the 19th of March and thanks to Bruce giving me a lift to the Maplin that did have the plugs I am now to the stage of final soldering tomorrow morning and then tomorrow afternoon if I am able to get all ten plugs and sockets that need soldering done I will start on the test runs to see how things go and get everything moving. Hopefully I will have video up tomorrow night, if not Saturday will be test and running day to see how thing go and get ready for doing some cutting. I still need to get the X axis IGUS chain to help protect the cables and will be cutting the brackets to hold that in place. Monday I will be ordering some HDPE to get bolted down to the sub bed and surfaced. Once that is done and the test cuts done I will be very busy.

Too right you will. I need brackets, supports, holders ..........:rofl:

I have to say that the machine is looking awesome.

Well Y and Z axis are up and running and responding to both jog and direct co-ord's input. Working on tracking down why I am not getting lock on the A and X axis screws and hopefully will have video of a full functional unit later this afternoon. As it is 5m/min is rather impressive and the machine does not shimmy at all. Need to design some cable guides for the Kress cable that will also serve for when I up grade to a spindle. Tracking down wiring gremlins is not fun what so ever at all and even though I know I tightened wires properly they seem to find ways of getting loose. Keeping at it an hoping to be done with this part soon.

Things that small which weigh the same as a small car tend to NOT shimmy.!!. . . . . . They just try to TIP the shed over.:dance:

When you do get the X axis going don't try going straight to 5mtr/min, twin screws setups tend to need a slight safety margin to be sure one motor doesn't stall which can really screw the gantry up bad.
With 5mm pitch screws your near max rpm and less torque, your gantry ain't over heavy but it ain't light weight either so tread carefull when your approaching 5mtr/min. If you don't need 5mtr/min then I'd say back it off just for good measure.!

Great Build! If you don't mind me asking what is your total cost? And can you break the cost down to parts? And suppliers?

I really love this build, all the best today!

Well Folks,

It is late tonight and much chasing the Gremlins. It runs and is zeroed on all axi'. I will get some video up tomorrow afternoon or evening of it running out the test pattern I am going to be using to see how it handles different speeds. As Jazz suspected, when the gantry comes to a stop from speed the shop shimmy's a bit. Currently have gotten Y and Z ups to 3500mm/min no problems and Y an additional 500mm more without me getting to nervous (at 1250mm^2min acceleration it moves fast). I am tired and going to bed.

Well Folks here is the promised video of some of the Test bed running I did today. This video takes it up to 4m/min run speed going in 500mm/ step ups from 2500mm/min start. I do not have video of the 5m/min run I did after that as was very careful with that one as did not want anything to wrong so had one hand on the e-stop and the other checking as able to do safely to insure nothing was over heating. Already have done a light tightening of the belts as was expected to be needed. I am going to be ordering the HDPE tomorrow for the cutting area bed and also a surfacing bit to surface it with (any suggestions up to a 8mm shaft would be useful (don't have 7mm collet but do have 1/4"). Then it is cutting jigs and parts. I will be posting more video as able.
