    Inductive linear scale

    Replace all those caps and check the resistance of that large resistor in the center of the pcb (if you see any heating on others, check them too). Resistance can be decoded by the color stripes, but if they are burned you have to guestimate. It looks bit crusty. I don't think there could be...

    CNC lathe tool nose compensation (G41/G42) troubles

    That seems to be typo only on this example, maybe on some testing too though (it was very confusing). I actually did the program today with I K just to be sure it was not the radius mode messing up. Oh well, it is a bugger for such a simple thing. I suck at math so is there any calculators for...

    CNC lathe tool nose compensation (G41/G42) troubles

    Thanks for the info, there is not a lot of material regarding lathe TNR available and probably the reason is its complexities..Lathe is a no name chinese crap, not produced anymore, but was cheap too! I actually just realized that it does the G02 and G03 backwards, 02 produces counterclockwise...

    CNC lathe tool nose compensation (G41/G42) troubles

    Hello, Now i've been trying to find any guides with varying situations, but nothing so far, everything describes the tool nose 3 with run of the mill profile turning. I also suspect that the crappy lathe i am using does not properly compute certain situations and might be the culprit here, but...

    Brother B00 sub-programs above 9000

    G100 tool change position is given by the XY command and it can either be a safe location or next movement position if you are aiming for quick chip to chip. R can be specified, where the retraction happens before XY movement. If no R is given, then the setting from user parameter is used...

    BT30 pullstuds

    I have 20 year old specimen which has ran mix of both angles just fine, so it will not break the machine right away.

    Advice needed on buying a new or used Tormach CNC Mill

    I think the rush is your worst enemy here, if there is a way to alleviate it somehow. Like if the part you were talking about is not very complicated, you could arguably start off with quite inexpensive manual milling machine, even new one. I had an option to use my friends decent manual milling...

    Where to find Imperial taps with metric shanks at a reasonable price?

    Well i bought a nice set of square key collets, M4 - M14 and that was the day i learned something new about taps and that is the variation in shank sizes. I have yet used a single one of them as none of taps i buy is correctly sized. Typically the mismatch is about 0.1mm (shank oversized, for...

    Best trick to adjust lathe serrated jaws quickly?

    All i have is a 4 position tool changer..:) With shims and all. Especially if boring is needed, the natural directionality is different and forces to remove even the main tool. Not great but acceptable for hobby use. I tested this method and it works wonders, it is enough just to have any tool...

    Best trick to adjust lathe serrated jaws quickly?

    Thanks for the answers, many ways to skin the cat it seems! Using the lathe tool with MDI as an indicator is intriguing, have to try that one out. This necessitates a tool with correct diameter which is not always the case though. Perhaps i could create some sort of stick protruding from...

    Best trick to adjust lathe serrated jaws quickly?

    Hi, I have been wondering how the professionals handle adjusting the CNC jaws which have serrated back edges for locking. There is no position indicators on my jaws and it often takes about 4 tries before they are in a correct spot when changing the diameters of stock. Do you have some sort of...

    New machine day - Brother S700X2 (UK install)

    You could easily route airblast or mist into 2 of these nozzles and only use 3 nozzles for cooling as 5 is overkill. I kept the left original arm and it provides sideways/backside coolant to the general area.

    New machine day - Brother S700X2 (UK install)

    If you get bored on adjusting those spray heads for different elevations, i made a fixed block with 5 nozzles on the backside of the spindle for myself, it was fantastic addition. It is for older brother machine though, might be different.

    Used Robodrill vs Brother

    When buying older models, the 3D paths might be slightly limited. For example i have TC-S2B-O and it supports only 3 axis simultaneous movement with 3+1 config. The additional axis is meant to be used for part flipping essentially and the Z axis limitation will affect the work holding principles...

    Issue Sending programs to an Older controller

    All of the cheap USB adapters kinda work, but if you want true RS-232 emulators you have to buy things like MOXA adapters which attempt to mimic all of the electronical behaviours that true hardware RS-232 port would have. These can connect to wireless or LAN ports too, so they are very flexible...
